What is contained in a lockout kit?

The correct answer pertains to devices specifically designed for tagging and locking out equipment. A lockout kit is crucial for ensuring safety during maintenance or repair of machinery and equipment. When technicians need to perform work on potentially hazardous machinery, they use lockout devices to secure the equipment in a safe state. These devices can include padlocks, hasps, and tags that clearly communicate that maintenance is being performed and that the equipment should not be operated. This practice is a vital component of workplace safety protocols, as it helps prevent accidental energization or startup of the equipment, thereby protecting workers from injury.

The other options are unrelated to the primary purpose of a lockout kit. Tools for opening locked doors are not necessary in the context of equipment maintenance and safety, emergency medical supplies are focused on health emergencies rather than mechanical safety, and firefighting tools serve a completely different function related to fire suppression rather than equipment lockout procedures.
