Pneumatic lockout valves control the compressed air required by production equipment.
Pneumatic energy, just like other energy sources, can be hazardous to workers. In fact, OSHA reports hundreds of injuries annually due to mishandling of this type of energy. As such, OSHA included the proper servicing and maintenance of machines and equipment that may release pneumatic energy in their 29 CFR 1910.147 standard.
Combining these pneumatic lockout valves with a well-designed lockout tagout procedure can prevent OSHA from quoting the facility for improper hazardous energy management.
