Passage of the OSH Act and Changes in Industrial Hygiene Evaluation
The passage of the Occupational Safety and Health (OSH) Act in 1970 brought about significant changes in the way industrial hygienists evaluated health hazards at facilities covered by the Act. Prior to the OSH Act, there was no comprehensive federal legislation addressing occupational safety and health in the United States. The OSH Act established the Occupational Safety and Health Administration (OSHA), which was tasked with ensuring safe and healthy working conditions for employees.
One of the major changes brought about by the OSH Act was the requirement for employers to establish and maintain programs to identify, evaluate, and control workplace hazards. This had a direct impact on industrial hygienists, as it placed a greater emphasis on hazard evaluation and control. Industrial hygienists became responsible for assessing health hazards in the workplace and implementing control measures to mitigate risks.
The OSH Act also mandated the development of permissible exposure limits (PELs) for hazardous substances. PELs are the maximum allowable concentration of a hazardous substance to which workers can be exposed over a specific time period. Before the OSH Act, there were no standardized exposure limits, making it challenging for industrial hygienists to evaluate health hazards consistently. The establishment of PELs provided clear guidelines for industrial hygienists to assess and manage chemical exposures in the workplace.
In addition to PELs, the OSH Act required employers to provide medical surveillance and monitoring for employees exposed to certain hazardous substances. This placed an increased emphasis on monitoring and tracking employee health to identify potential adverse effects from occupational exposures. Industrial hygienists were instrumental in implementing these medical surveillance programs and ensuring that employees’ health was monitored effectively.
Overall, the passage of the OSH Act revolutionized the way industrial hygienists evaluated health hazards in facilities covered by the Act. It established clear guidelines, such as PELs and medical surveillance requirements, that enhanced the ability of industrial hygienists to identify, assess, and control health hazards in the workplace.
Two Important OSHA Regulations for Industrial Hygienists
As an industrial hygienist, there are numerous Occupational Safety and Health Administration (OSHA) regulations that are essential for reducing the risk of health hazards in the workplace. However, two regulations stand out as particularly important:
Hazard Communication Standard (HCS) – 29 CFR 1910.1200: The HCS ensures that employees are informed about the hazardous chemicals they work with or may encounter in the workplace. It requires employers to develop a comprehensive hazard communication program that includes labeling of containers, safety data sheets (SDS) for each hazardous chemical, and employee training. This regulation is crucial for industrial hygienists as it allows them to effectively assess and communicate chemical hazards to workers, enabling proper handling, storage, and use of hazardous substances.
Respiratory Protection Standard – 29 CFR 1910.134: This regulation establishes requirements for employers to implement respiratory protection programs when employees are exposed to respiratory hazards. It outlines criteria for selecting appropriate respiratory protective equipment, fit testing procedures, medical evaluations, training, and maintenance of respiratory protection equipment. Industrial hygienists must ensure compliance with this regulation to protect workers from respiratory hazards such as airborne contaminants or oxygen-deficient atmospheres.
These two regulations are vital for industrial hygienists as they address fundamental aspects of hazard communication and respiratory protection. By adhering to these standards, industrial hygienists can effectively mitigate risks associated with hazardous chemicals and airborne contaminants.
Toxicology Data for Risk Assessment by Industrial Hygienists
Industrial hygienists rely on various forms of toxicology data to perform risk assessments for occupational chemical exposures. Three types of toxicology data that are commonly used include:
Acute Toxicity Data: Acute toxicity data provides information on the immediate effects of short-term exposure to a chemical. This data includes toxicity studies conducted on animals or humans that measure lethal dose (LD50) or lethal concentration (LC50), as well as information on symptoms and effects observed at different exposure levels. Industrial hygienists use this data to assess the potential severity of acute health effects resulting from chemical exposures.
Chronic Toxicity Data: Chronic toxicity data examines the long-term effects of repeated or prolonged exposure to a chemical over an extended period. This data is typically derived from animal studies or epidemiological studies on humans. It includes information on carcinogenicity, reproductive toxicity, organ toxicity, and other chronic health effects. Industrial hygienists use this data to evaluate the potential long-term risks associated with continuous exposure to a chemical in the workplace.
Exposure Limits and Thresholds: Exposure limits and thresholds provide guidance on acceptable exposure levels for various chemicals. These limits include permissible exposure limits (PELs), threshold limit values (TLVs), recommended exposure limits (RELs), and other similar guidelines established by regulatory agencies or professional organizations. Industrial hygienists use these limits as benchmarks to compare actual exposure levels in the workplace against safe levels, enabling them to determine if additional control measures are necessary.
By utilizing these forms of toxicology data, industrial hygienists can assess the risks associated with occupational chemical exposures more comprehensively. These data sources help them understand the potential immediate and long-term health effects of chemicals, as well as set exposure limits that promote worker safety.
Managing Industrial Hygiene Sampling without a Full-Time IH
In situations where a facility does not have a full-time industrial hygienist (IH) on staff, there are several approaches that can be taken to manage initial and ongoing industrial hygiene sampling:
Outsource Sampling Services: The facility can hire external consultants or industrial hygiene companies to conduct initial and ongoing sampling as needed. These professionals can perform exposure assessments, air monitoring, noise level measurements, and other necessary sampling activities. By outsourcing these services, the facility can ensure that comprehensive sampling is conducted by experts in industrial hygiene.
Training Internal Staff: If hiring external consultants is not feasible due to budget constraints, existing staff members can be trained on basic industrial hygiene principles and sampling techniques. This can enable them to conduct initial sampling under the guidance of external consultants or through collaboration with other organizations or institutions that specialize in industrial hygiene. However, it is essential to recognize that training internal staff does not replace the expertise and experience provided by a dedicated IH.
Utilize Available Resources: Facilities without a full-time IH can leverage resources provided by regulatory agencies such as OSHA or other industry-specific organizations. These resources often include guidance documents, sampling protocols, and best practices for conducting industrial hygiene sampling. By following these resources, facilities can implement their own sampling programs based on established standards.
Incorporating an IH program into an existing safety and health management system requires integration with existing processes and procedures. It is crucial to ensure that occupational health risks are considered alongside safety hazards in all aspects of the management system. This can be achieved by aligning IH activities with existing risk assessment processes, providing IH training as part of employee orientation and ongoing education programs, incorporating IH metrics into performance evaluations, and regularly reviewing IH program effectiveness.
In conclusion, while having a full-time IH provides dedicated expertise in managing industrial hygiene sampling and assessments, facilities without this resource can still effectively manage initial and ongoing sampling by outsourcing services, training internal staff, or utilizing available resources. Incorporating an IH program into an existing safety and health management system requires integration at various levels to ensure comprehensive risk assessment and control measures are implemented throughout the facility.
