While the extent of responsibility under the law of staffing agencies and host employers is dependent on the specific facts of each case, staffing agencies and host employers are jointly responsible for maintaining a safe work environment for temporary workers - including, for example, ensuring that OSHA's training, hazard communication, and recordkeeping requirements are fulfilled.
To ensure that there is a clear understanding of each employer's role in protecting employees, OSHA recommends that the temporary staffing agency and the host employer set out their respective responsibilities for compliance with applicable OSHA standards in their contract. Including such terms in a contract will ensure that each employer complies with all relevant regulatory requirements, thereby avoiding confusion as to the employer's obligations.
