No, they cannot. In IDLH situations supplied air respirators or SCBA's must be used.
Level A protection is required when the highest level of respiratory, skin, eye, and mucous membrane protection is needed due to the presence of identified vapors, gases, particulates, or liquid splash that pose a high risk. Level B protection is used when the highest respiratory protection is needed, but a lesser degree of skin protection is acceptable. Level C protection is suitable when respiratory protection is required, but skin and eye contact are unlikely.
The M50 gas mask is not specifically OSHA certified; rather, it is certified by the National Institute for Occupational Safety and Health (NIOSH) for respiratory protection. OSHA standards require that respirators meet NIOSH certification for workplace safety. While the M50 is widely used by military and certain civilian agencies for protection against chemical and biological agents, its certification pertains to NIOSH rather than direct OSHA endorsement.

Two types of respirators are generally worn when spraying paint; air-purifying and air-supplied. If oxygen levels are not adequate, the air-supplying respirator must be used. The type of air-purifying respirators that are used during paint spraying remove particulate vapors and gas, and are called Particulate Vapor and Gas Removing Air-Purifying Respirators.

Employers are generally required to pay for personal protective equipment (PPE) that is necessary for employees to perform their jobs safely. This includes items such as helmets, gloves, eye protection, hearing protection, and respiratory protection. Additionally, if the PPE is specifically needed for the job and not used for personal purposes, employers must cover the costs. However, there may be exceptions based on the specific regulations and circumstances within different industries.
