Final answer:
OSHA requires employers to annually review and update their exposure control plan, and also when there are new procedures or positions affecting occupational exposure. These updates are part of OSHA's regulations that ensure workers' safety by mandating training, recordkeeping, provision of PPE, and more.
Step-by-step explanation:
The Occupational Safety and Health Administration (OSHA) requires employers to review and update their exposure control plan at least annually, and whenever necessary to reflect new or modified tasks and procedures which affect occupational exposure and to address new or revised employee positions with occupational exposure. This is part of OSHA's broader mandate to ensure that employers provide a safe workplace and obey all relevant OSHA standards and regulations. Part of these regulations include the responsibility of employers to provide safety training, keep accurate records of work-related injuries and illnesses, and provide required personal protective equipment at no cost to workers.
OSHA standards are in place to protect workers from a wide range of serious hazards, which include mechanisms like fall protection, chemical exposure limits, and the use of guards on machines. Noteworthy is the fact that employers must also comply with the General Duty Clause of the OSH Act, ensuring that workplaces are free from serious recognized hazards.
