SCHOOL SAFETY PROCEDURES FOR ART AND INDUSTRIAL ART PROGRAMS CHAPTER 5. LAWS AND REGULATIONS A wide variety of federal, state and local agencies administer laws and regulations on health and safety that apply to schools. In addition, in case of accident, teachers and schools can be subject to lawsuits if negligence is involved. This chapter will discuss the most important of these laws and relevant government agencies. OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) Employers are required by the federal Occupational Safety and Health Act of 1970 (OSHAct) "to ensure as far as possible every working man and woman in the Nation safe and healthful working conditions". The Occupational Safety and Health Administration (OSHA), a federal agency, has the responsibility for administering OSHAct, issuing standards on health and safety, and carrying out inspections to enforce the regulations and law. OSHA can fine employers who do not comply. Coverage of OSHAct applies to all private employers and their employees in the 50 states, the District of Columbia, Puerto Rico, and all other U.S. territories. In 23 states with OSHA-approved state plans, OSHA has delegated its authority to enforce OSHAct. OSHA-approved state plans must cover state and local government employees, such as public school teachers. State plans may also cover private employers and their employees. Once federal OSHA has adopted a regulation, these states must adopt a comparable standard within six months of the publication date of a final standard. States with OSHA-approved state plans include: Alaska, Arizona, California, Hawaii, Indiana, Iowa, Kentucky, Maryland, Michigan, Minnesota, Nevada, New Mexico, New York, North Carolina, Oregon, Puerto Rico, South Carolina, Tennessee, Utah, Vermont, Virginia, Virgin Islands, Washington, and Wyoming. Note that OSHA does not protect students, only employees. Rights and Responsibilities Under OSHAct, employers are responsible for keeping a hazard-free workplace, knowing and obeying OSHA standards, informing employees about OSHA and their rights, keeping appropriate records, informing OSHA of fatalities and five or more injuries requiring hospitalizations, posting citations, and abating citations. Employees are responsible for following employer health and safety rules and OSHA standards, wearing required personal protective equipment, reporting hazardous conditions and accidents to their supervisor, and cooperating with OSHA compliance officers. Employees have the right to see copies of applicable OSHA standards, to request information on hazards and precautions, to request OSHA to make an inspection if it is believed there are hazardous conditions or violations of OSHA standards, to have his or her name kept confidential when filing an OSHA complaint, to have an authorized employee representative present during inspections, to have access to monitoring and medical records, and to not be discriminated against for exercising these rights. OSHA Standards The general duty clause of OSHAct states that each employer "shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees." This general duty clause can be used by compliance officers when there is no specific OSHA standard. OSHA also promulgates and enforces specific health and safety standards. OSHA standards cover such areas as emergency plans, fire safety, machine guarding, flammable and combustible liquids, spray finishing, welding, sanitation, toxic and hazardous substances, etc. These General Industry Standards are found in 29 CFR 1910. Many applicable OSHA standards were discussed in Chapter 4. OSHA standards are available from OSHA offices. Toxic and Hazardous Substance Standards Subpart Z, Toxic and Hazardous Substances, of the OSHA standards lists the Permissible Exposure Limits (PELs) for several hundred chemicals (CFR 1910.1000). These PELs were recently revised, mostly to reflect changes in the Threshold Limit Values (TLVs) of the American Conference for Governmental Industrial Hygienists (although 1992 court decisions have challenged these changes). Prior to this revision, most PELs were based on 1968 TLVs. The PELs are legal standards. TLVs are defined as "airborne concentrations of substances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed day after day without adverse effect." One problem with TLVs for many chemicals is that the manufacturers of those chemicals had a major say in the TLV development. As a result there is considerable controversy over the adequacy of the resulting TLVs. In addition, they do not protect sensitive workers, and can not be applied to children. In order to apply the numerical TLVs (or PELs), there must be air sampling to determine the concentration in air of that chemical. In addition to the PELs, Subpart Z has specific standards for many hazardous substances, including asbestos, lead, cadmium, formaldehyde, and many other carcinogens. Inspections OSHA has the right to inspect any workplace without advance notice. There are several types of inspections: * imminent danger; * fatality and multiple injuries; * valid employee complaints; * special emphasis programs (aimed at high risk industries); and * random inspection programs. The OSHA inspector can issue citations and penalties for violation of OSHA standards. These citations usually give an abatement date for correction of the violations. The size of the penalty depends on the type of the violation, which includes other than serious, serious, willful, and repeated violations, and failure to correct a prior violation. The citation and penalty (or lack of same) can be appealed by the employer. Employees or unions can contest abatement times for correcting violations. Hazard Communication Standard The OSHA Hazard Communication Standard (29 CFR 1910.1200) applies to all employees in the United States who are exposed or potentially exposed to hazardous substances at their workplace. The purpose of the hazard communication rule is to ensure that the hazards of all chemicals produced or imported are evaluated, and that information concerning their hazards is transmitted to employers and employees by means of comprehensive, written hazard communication programs. The OSHA Hazard Communications Standard was discussed in detail in Chapter 3. Employee Exposure Access and Medical Records OSHA requires that employers allow employees and their designated representatives to examine and copy employee exposure records and medical records (29 CFR 1910.20). Exposure records includes air sampling and other workplace environmental monitoring data and reports, biological monitoring results, Material Safety Data Sheets, and any other information related to an employee's exposure to toxic substances and harmful physical agents. Medical records means any records concerning the health of an employee, and includes medical examinations, questionnaires, physician's opinions, etc. To release medical records to designated representatives such as unions, the employee must sign a release form. The employer must keep medical records for the period of employment plus 30 years, and employee exposure records for 30 years. Record-keeping and Reporting OSHA requires that most employers keep records of occupational illnesses and injuries on OSHA forms 200 and 101 (29 CFR 1904). Employers with fewer than 10 employees and employers in certain low risk industries - including schools - do not have to follow these record-keeping requirements. However, if an on-the-job accident results in the death of an employee or in the hospitalization of 5 or more employees, all employers must report the accident in detail to the nearest OSHA office within 48 hours (29 CFR 1904.8). Voluntary Compliance Program OSHA funds a voluntary compliance program, usually operated by the state departments of labor. Under this free program, a voluntary compliance officer will conduct an inspection of the workplace at the request of the employer, and make recommendations for correction of any hazards. Employers working with this program may be exempt from OSHA general schedule enforcement inspections for a period of one year. The voluntary compliance program does not report to OSHA any violations found, except in cases of imminent hazard which could involve death or serious injury. Appendix 3 lists the voluntary compliance offices in each state. STATE RIGHT-TO-KNOW LAWS State right-to-know laws were preempted by the OSHA Hazard Communication Standard except for public employees in states with OSHA-approved state plans. The New York State Right To Know Law (RTK), for example, requires public employers to 1) notify workers of their rights to information on toxic substances they are exposed to; 2) respond in writing to employee requests about toxic substances within 72 hours; 3) conduct annual training of employees in the identity, properties and safe use of toxic substances that the employees might encounter in their work; and 4) keep records of employees exposure to substances with enforceable exposure standards under OSHA's Subpart Z, Toxic and Hazardous Substances for 40 years. The record-keeping requirements also apply to private employers. Both the OSHA Hazard Communication Standard and the NYS RTK Law are enforced for public employers in New York, for example public schools. Contact the regional OSHA office in your state (or the state Health or Labor Department) to find out if there is a Right-To-Know Law in your state. NATIONAL INSTITUTE FOR OCCUPATIONAL SAFETY AND HEALTH (NIOSH) The National Institute for Occupational Safety and Health was established by OSHAct to conduct research on occupational health and safety, to provide technical assistance to OSHA, and to recommend standards for OSHA to adopt. NIOSH can make workplace investigations as part of this research. It can require that employers measure their employees' exposures and provide medical examinations of employees (at NIOSH expense). NIOSH also certifies respirators. NIOSH provides technical assistance to employers and employees. Employers or three or more employees can request a Health Hazard Evaluation if they suspect that health hazards exist in the workplace. NIOSH will come in and conduct any air monitoring and medical examinations necessary. In addition, employers can request a Technical Assistance inspection, which is a more limited version of the Health Hazard Evaluation. NIOSH also provides information to employers and employees upon request and has a wide variety of literature. See Appendix 2 for a list of NIOSH offices. WORKERS COMPENSATION LAWS Most employees in the United States are required to be covered by state workers' compensation laws. These laws provide a variety of benefits for job-related injuries and illnesses, including benefits for medical expenses, wage replacement, loss of limbs (or their use), rehabilitation and survivor's benefits in case of death. These laws vary from state to state. Workers' compensation is a "no fault" insurance system, meaning an injured employee can collect without having to prove it was the employer's fault. In addition, the injured employee can collect benefits even if the injury was his or her fault. In return, the employer is protected from lawsuits for negligence. Thus workers' compensation is the sole remedy for injured employees with respect to their employer. (See the section on Liability for information on lawsuits against other parties besides the employer.) What Is Covered? Injuries are covered under workers' compensation if they are job-related. The usual requirements are that the injury result from an accident arising out of and in the course of employment. The actual injury does not have to occur on the job site. For example, a car accident on the road during a delivery for the employer would be covered. Occupational illnesses may also be covered. The extent of coverage and what illnesses are covered varies widely from state to state. In New York State, the illness does not have to be solely caused by something on the job, but the job has to substantially contribute to the illness. A classic example of a compensable occupational illness is contact dermatitis from exposure to chemicals. There are usually statutes of limitations for filing claims for occupational diseases. In New York State, a worker may file a claim for up to 2 years after becoming aware that the disease was caused by the job. An injured employee has the right to file a workers' compensation claim with the state workers' compensation board if he or she thinks the injury is work-related, whether or not the employer agrees. If the employer does not think the injury or illness was work-related, then the employer can challenge the claim. Insurance Carriers There are a variety of ways to be covered under workers' compensation: private carriers, state funds, and self-insurance. State laws vary widely in the types of carriers permitted. Some states have an exclusive state fund, which is a non-profit agency that provides workers' compensation insurance for employers. Other states allow private insurance companies to provide workers compensation and have non-exclusive State Funds which must provide coverage to employers. New York State allows private carriers, and has a State Insurance Fund. Large employers often have self insurance, meaning they cover themselves for workers' compensation benefits. Of course, these plans have to meet state regulations. The premiums for workers' compensation insurance is paid entirely by the employer. The premium size depends on the company's experience rating. This depends on the number of workers' compensation claims that have been filed by the company and on the average for the industry. CONSUMER PRODUCT SAFETY COMMISSION The Consumer Product Safety Commission (CPSC) administers a number of laws affecting consumer and children's safety. These laws regulate consumer products, including science and art instructional materials, playground equipment, toys, etc. This book will only discuss the laws affecting art and industrial arts materials. The Federal Hazardous Substances Act The Federal Hazardous Substances Act (FHSA) cover the labeling of consumer products, including art materials used in schools. The original FHSA only required labeling for acute or immediate hazards, especially ingestion. Under this law, asbestos could have been labeled non-toxic. The FHSA required the labeling to include the signal word DANGER (for highly toxic materials), WARNING or CAUTION; the names of chemicals with acute hazards, warnings, precautions, and first aid information. The Labeling of Hazardous Art Materials Act In 1983, the American Society for Testing and Materials (ASTM) adopted a voluntary standard, ASTM D-4236 Standard Practice for Labeling Art Materials for Chronic Health Hazards. Many fine art materials manufacturers adopted this standard through the Health Label program of the Arts and Crafts Materials Institute. Unfortunately most arts and craft manufacturers of the more hazardous art materials did not participate in this voluntary program. As a result, during the mid 1980's, several states passed laws requiring that art and craft manufacturers list the chronic hazards of their materials on the label, and banned hazardous art supplies in elementary schools. In 1988, the U.S. Congress amended the FHSA by passing the Labeling of Hazardous Art Materials Act which adopted ASTM D-4236 into law (Public Law 100-795), thus requiring art and craft manufacturers to list the chronic hazards as well as acute hazards. The label of chronically hazardous art materials must list the following: * the signal word WARNING (unless the signal word DANGER is already required; * the chemical names of the chronically hazardous ingredients; * a list of specific potential hazards; * safe handling instructions; * a list of sensitizing chemicals that can cause allergic reactions; and * sources for further information. Art and materials in conformance with this law must carry the statement "Conforms to ASTM D-4236" or the equivalent. If the art or craft material contains hazardous materials, it must also state that it is not suitable for use by children. The Labeling of Hazardous Art Materials Act also allows the Consumer Product Safety Commission to obtain a court injunction against any school purchasing chronically toxic art supplies for use in elementary school. ENVIRONMENTAL PROTECTION AGENCY (EPA) The Environmental Protection Agency (EPA) regulates the disposal of hazardous waste under the Resource Conservation and Recovery Act, and industrial wastewater discharges under the Clean Water Act and Water Pollution Act. The EPA also regulates emergency planning and community right-to-know under the Superfund Amendments and Reauthorization Act. Resource and Conservation Recovery Act (RCRA) Legally, schools have to properly dispose of hazardous waste. This section discusses waste management laws. Information on waste management and disposal procedures is discussed in Chapter 10. The Resources and Conservation Recovery Act (RCRA) was enacted in 1976 as an amendment to the Solid Waste Disposal Act. The basic goals of RCRA are: to protect human health and the environment, to reduce waste, to conserve energy and natural resources, and to reduce or eliminate the generation of hazardous waste as expeditiously as possible. The RCRA regulations are found in Part 240 of Title 40 of the Code of Federal Regulations (40 CFR 240). Subtitle C of Part 240 regulates the management of hazardous waste through a "cradle-to-grave" system of statutory and regulatory requirements for the identification of hazardous waste and generators, amongst other requirements. Using a waste manifest system, the hazardous waste is tracked through its production, transportation, and final disposal. The responsibility for administering RCRA rests with the individual states. Most of the states' hazardous waste programs directly resemble RCRA. One can contact individual state environmental offices to elucidate particular differences between states. The relevant offices may be named a variety of names, for example: the NYS Department Environmental Conservation (NYS DEC), and Wyoming Department of Environmental Quality (WY DEQ). Hazardous waste generators are the first link in the cradle-to-grave chain of hazardous waste management under RCRA. There are different categories of producers of hazardous waste. The basic distinctions center around the amounts of hazardous waste produced. As written in 40 CFR Part 261.5, there are three categories of hazardous waste generators. 1. Large Quantity Generators (LQGs): LQGs produce more than 1000 kilograms per month (kg/month) of hazardous waste, or more than 1 kg/month of acutely hazardous waste. LQGs must obtain a US EPA identification number from state hazardous waste management agencies or EPA regional offices. These numbers are part of a national data base on hazardous waste activities. They must comply with storage time, quantity, handling and record-keeping (manifest) requirements. In addition, LQGs must have an emergency/contingency plan in case of spills of stored hazardous waste (40 CFR 262.34). See the Spills and Leaks section of Chapter 4. 2. Small Quantity Generators (SQGs): SQGs produce more than 100 kg/month and less than 1000 kg/month, and accumulate less than 6,000 kg. SQGs must obtain a US EPA identification number from state hazardous waste management agencies or EPA regional offices. These numbers are part of a national data base on hazardous waste activities. They must also comply with storage time, quantity, handling and record-keeping (manifest) requirements. SQGs must also have an emergency/contingency plan in case of spills of stored hazardous waste (40 CFR 262.34). 3. Conditionally Exempt Small Quantity Generators (CESQGs): CESQGs produce less than 100 kg/month (220 pounds) of hazardous waste, and less than 1 kg/month (2.2 pounds) of acutely hazardous waste. They are "conditionally exempt" from Subtitle C, and the manifest system. Notwithstanding, CESQGs must identify all hazardous waste, never accumulate more than 1000 kg, treat or dispose of their waste on-site or make sure that the waste is sent to an approved facility. This includes permitted or interim status treatment storage or disposal facilities (TSDFs), permitted municipal or industrial solid waste facility, or a recycling facility. Not all states, however, recognize a difference in requirements for CESQGs compared to SQGs. Check your state laws for more stringent requirements. Clean Water Act (CWA) The EPA has developed regulations that establish the basis for wastewater management under the Clean Water Act of 1977. Each municipality develops and enforces programs regulating sewer and wastewater treatment. For specific information on local regulations, one must consult the local Public Works and their own Department of Environmental Protection. The federal Water Pollution Act of 1972, and the Clean Water Act of 1977 were enacted with the goal to "restore and maintain the chemical, physical and biological integrity of the nation's waters". Title 40 CFR Section 402 requires that publicly-owned treatment works (POTWs) or sewage treatment plants establish local pretreatment programs to ensure compliance. The pretreatment requirements are given in Section 403. All POTWs are required to develop local sewer use codes. These limits are designed to reflect the particular local environmental conditions of the area. Sewer codes will vary according to where POTW discharges are made. Many states are allowed to administer their own approved programs, and may have more stringent requirements. Superfund Amendments and Reauthorization Act The Superfund Amendments and Reauthorization Act of 1986 (SARA) revised and extended the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), commonly known as Superfund. Title III of SARA established authority for emergency planning and preparedness, emergency notification reporting, Community Right-to-Know reporting, and toxic chemical release reporting. Community Right-to-Know reporting: Section 311 of SARA requires all facilities, including schools, which are covered by OSHA's Hazard Communication Standard to submit Material Safety Data Sheets (MSDSs) or a list of hazardous chemicals to the local emergency planning committee (LEPC), the state emergency response committee (SERC), and the local fire department if the chemical is present in the facility in amounts exceeding reporting thresholds. Section 312 can impose further reporting requirements. The reporting thresholds are 500 pounds for EPA-designated Extremely Hazardous Substances or the threshold planning quantity (TPQ) for that chemical, whichever is lower, and 10,000 pounds for chemicals that are not on the Extremely Hazardous Substances List. Most schools do not store chemicals in quantities exceeding the reporting thresholds. See the Material Safety Data Sheet section of Chapter 3 for a list of chemicals that could be in excess of the reporting thresholds. Emergency notification reporting: Section 304 of SARA requires notification of the National Response Center if there is a toxic release into the environment of a chemical on the CERCLA list in excess of its Reportable Quantity, and of local emergency authorities (LEPC, SERC) if the chemical is on the Extremely Hazardous Substance List. See the Spills and Leaks section of Chapter 4 for emergency notification requirements. AMERICANS WITH DISABILITIES ACT (ADA) The Americans with Disabilities Act of 1990 (ADA) was signed into law on July 26, 1990. This act gives civil rights to individuals with disabilities similar to that provided for people on the basis of sex, race, national origin and religion. The ADA has several anti-discrimination sections that are relevant to schools: 1) Title IV, dealing with employment; 2) Title II, dealing with public services; and 3) Title III, dealing with public accommodations operated by private entities. Employment As of July 26, 1992, employers with 25 or more employees are prohibited from discriminating against qualified individuals with a disability in the following areas: * job application procedures; * hiring, advancement or discharge of employees; * employee compensation; * job training; and * other terms, conditions, and privileges of employment. Disability definition: According to the ADA, a disability is: 1) a physical or mental impairment that "substantially limits" one or more of the major life activities of an individual; 2) a record of such an impairment; or 3) being regarded as having such an impairment. Exclusions from this definition include compulsive gambling, and illnesses resulting from the current use of illegal drugs. Qualified job applicant: A "qualified job applicant with a disability" is "an individual with a disability who, with or without reasonable accommodation, can perform the essential functions of the employment position." The term "essential functions" refers to the "primary job duties that are intrinsic to the employment position." These essential functions should be spelled out in a job description. It is illegal to require physical abilities that actually are not required for the job. An employer may require as a job qualification that employees not pose a direct threat to the health or safety of themselves or others. To exclude a person with a disability on this basis, however, an employer would have to show the nature, severity, probability, and imminence of potential harm. Reasonable accommodation: The employer is required to make "reasonable accommodation" to the disability of an employee as long as such accommodation does not impose an "undue hardship" on the employer. Such accommodation can include making existing facilities accessible, job structuring, part-time or modified work hours, acquisition or modification of equipment, provision of qualified readers or interpreters, etc. If performing the essential job functions would have a high probability of substantial harm to the disabled person, an employer could exclude that person from a job unless reasonable accomodation would prevent harm. In art or industrial art classrooms, exposure to certain chemicals, especially solvents, may put certain individuals with disabilities or who are taking medications, at higher risk of illness than non-disabled individuals. For example, this can include people who have asthma or have chemical sensitivities. In these situations, reasonable accommodation could include installing extra precautions such as better ventilation or substituting safer chemicals in order to protect these individuals. These provisions would also apply to someone who becomes ill or injured as a result of his or her job. Medical examinations and questions: An employer may not use medical examinations or questions in a discriminatory manner. Pre-employment physical examinations and questions about disabilities are prohibited, although an employer can ask if an applicant can perform job-related functions. An employer may require a preplacement medical examination after an employment offer is made, and the employment offer subjected to satisfactory results from the test, if all entering employees are subject to such examinations and the results kept confidential with certain exceptions (e.g. a supervisor's need to know about job restrictions). In order to exclude a person from a job because of the results of a medical examination, it must be shown that the examination is job-related, consistent with business necessity, and that reasonable accommodation can not solve the problem. Medical examinations and inquiries about an employee's disability are allowed if they are shown to be job-related and consistent with business necessity. Voluntary medical examinations as part of an employer's health program are allowed. Medical examinations required by federal, state or local law (e.g. OSHA-required medical surveillance) are allowed if they are job-related and a business necessity. Public Services Under Title II of the ADA, all public services must be made accessible, including public transportation. Schools come under the category of public services. The effective date of this section was January 26, 1992. In essence, schools receiving federal funds have had to be accessible for years under the requirements of Section 504 of the Rehabilitation Act of 1973, which prohibited discrimination on the basis of disability. This particularly applies to students. Public Accommodations Private schools which own, lease, lease to, or operate a place of public accommodation are prohibited from discriminating against individuals with disabilities. This can include auditoriums and classrooms open to community activities. This section also became effective January 26, 1992. Examples of discrimination would include eligibility criteria that would tend to screen out individuals or classes of individuals with disabilities, failure to make reasonable modifications in policies and procedures, failure to provide needed auxiliary aids and services, and failure to remove architectural and communications barriers which are "readily achievable". NEGLIGENCE LAWSUITS Lawsuits for negligence against schools where students or others have been injured are on the increase. Obvious questions are who can sue, who can be sued, and what constitutes negligence. Who Can Be Sued? As discussed under Workers' Compensation, if an employee is injured on the job, he or she cannot sue the employer (or other employees) - even if their negligence caused the accident, since workers' compensation is the sole remedy for employees. The injured employee, however, can sue independent contractors (individuals or companies) whose negligence was a cause of the accident. However, if a student is injured through the negligence of the school or its employees, then the student can sue the school and, sometimes, their teacher if the teacher was negligent. What Is Negligence? In general, to recover damages in a lawsuit, an injured student would have to prove there was an injury or illness, that there was negligence, and that the negligence caused the injury or illness. In most states, schools are held in loco parentis to students, which means that the school is acting like a parent and would have to take the same degree of precautions as a parent. Factors that could indicate negligence include lack of a safe working environment, lack of training of the students in the hazards of art materials and processes and suitable precautions, and lack of supervision of students.
