This training session on permit-required confined spaces is designed for construction workers designated as attendants for these spaces. You know that construction sites change constantly as the work progresses. That means confined spaces change, too. In fact, confined spaces can be created during the course of a project, even if none existed at the project’s start. This session will help you identify the hazards of confined space entry, including the signs, symptoms, behavioral effects, and consequences of hazard exposure.
Why “Permit-Required Confined Spaces in Construction: Attendant” Matters:
Understand new Occupational Safety and Health Administration (OSHA) requirements (29 CFR 1926 Subpart AA) that your employer must follow to keep construction workers safe.
Confined space accidents frequently result in death.
A large percentage of fatalities over the years have involved would-be rescuers without proper training or equipment.
Your confined space entrants could face life-threatening hazards, such as:
Flammable gas, vapor, mist, or dust at levels high enough to cause a fire or explosion;
Toxic gas, vapor, mist, or dust at levels high enough to cause illness or death if inhaled;
Oxygen levels below what you need to breathe, causing suffocation;
Liquids or flowing solids (e.g., sand) that could cover, bury, or smother;
Entrapping design (e.g. walls that curve in, floors that slope and taper down);
Heat high enough to cause exhaustion or heatstroke;
Noise that could damage hearing or make it hard to hear directions or warnings; and
Energy and/or equipment that could cause electrocution, fire, or explosion.
- Your primary responsibility as an attendant is the safety of the entrants.
- You must understand all of the potential hazards of the confined space where the operation is taking place.
- You should be able to detect the behavioral effects of various hazards on personnel in the space.
- You must stay in constant communication with the entrants while they are in the space.
- Finally, you should be able to perform nonentry rescue operations, as well as be able to summon the rescue team and prepare for their arrival.
