Final answer:
The use of oxygen for ventilation, cooling, and cleaning during welding and other hot work is restricted by OSHA regulations, due to the increased risk of fire and explosion.
Step-by-step explanation:
The statement is true. OSHA regulations do restrict the use of oxygen for ventilation, cooling, and cleaning during welding and other hot work. The improper use of oxygen can create serious hazards by intensifying a fire or explosion. For this reason, oxygen should never be used for purposes for which it isn’t specifically intended, such as ventilation, which can lead to unsafe levels of oxygen concentration and increase the risk of fire.
Employers must comply with OSHA standards to maintain a safe working environment by using appropriate engineering controls like ventilation systems, rather than misusing oxygen, to manage hazardous fumes. These safety procedures are essential for the protection of workers from the risks associated with welding and other operations that involve toxic fumes or fire hazards.
