The best and most effective method of chemical exposure control is to implement a comprehensive chemical safety program. Such a program should include a hazard assessment, engineering controls, administrative controls, proper personal protective equipment (PPE), and a medical surveillance program.
Hazard Assessment
A hazard assessment is the first step in any chemical safety program. This assessment helps identify potential chemical hazards and the associated risks. It should include an evaluation of the type and concentration of the chemicals present, the duration and frequency of exposure, and the potential for inhalation, ingestion, and skin contact.
Engineering Controls
Engineering controls are designed to reduce or eliminate exposure to chemicals by altering the work environment. Examples include ventilation systems, local exhaust systems, and process enclosures. These controls should be designed and implemented to ensure the safety of the workers.
Administrative Controls
Administrative controls involve the implementation of procedures and practices that reduce the potential for exposure. Examples include work practices, standard operating procedures, and training programs. Administrative controls should be regularly monitored and updated to ensure compliance with applicable regulations.
Personal Protective Equipment (PPE)
Personal protective equipment (PPE) is designed to protect workers from chemical exposure. It includes items such as gloves, respirators, eye protection, and chemical-resistant clothing. PPE should be properly selected, maintained, and used to ensure the safety of the workers.
Medical Surveillance Program
A medical surveillance program should be implemented to monitor the health of workers exposed to chemicals. This program should include pre-employment medical screening, periodic physical examinations, and laboratory testing. It should also include training on how to recognize the signs and symptoms of chemical exposure.
