Personal protective equipment (or PPE)
Ever wonder why hard hats are such a ubiquitous tool for people in all kinds of vastly different worksites? Federal authorities (in the form of the Occupational Safety and Health Administration) have set down strict laws requiring certain equipment in certain hazardous conditions. States' laws can supersede these laws, but only by making them stricter.
Hard hats – If your worksite normally requires a hard hat, that requirement is still in place in a confined space! Hard hats should be made especially for your work site – no bike helmets or sports helmets allowed. Kevlar and fiberglass work best, and each helmet should have a three-point chinstrap.
Hard-toed boots – Your work boots need to have good traction for confined space work – especially when dangerous chemicals are involved. Gas may settle toward the bottom of a floor, which can increase the safety risk if you trip and fall.
Hearing protection – If you would've needed it if there were no permit-requiring condition, then you need it now, too.
Personal Protective Equipment (PPE) Signs
Clearly designating areas where specific safety equipment is required helps protect workers’ and visitors’ health along with meeting regulatory standards and promoting productivity.
Eye protection – If splintering materials, chemicals or flammability are a danger, goggles might be necessary. Again, if you'd be wearing them on your site anyway, wear them in the confined space.
Work gloves – The type of gloves required may depend on conditions at your site. Fire retardant gloves may be advisable if you're working in a flammable atmosphere; sturdy leather work gloves can work for non-permit-requiring sites, as can military flight gloves, which offer flexibility and a measure of flame resistance.
Supplied air respirator (SAR) or self-contained breathing apparatus (SCBA) – SCUBA for landlubbers. SCBA/SAR are used either when the air is IDLH (Immediately Dangerous to Life or Health) or when you aren't certain of the air quality. A minimum of 30 minutes of breathing capacity is usual for confined-space SCBA systems, and should be pressure-demand SCBAs (which maintain pressure while the user inhales and exhales, admitting no outside air.
Chemical suit – These special, airtight suits are typically adaptable for use with SCBA, for use in chemically hazardous environments or places with dangerous gas leaks. These often come with either built-in boots or socks to maintain tight air control, and are hooded to maintain air quality (and keep chemicals off your skin).
PPE signs can help ensure that workers on your site are using the appropriate equipment when they're working in dangerous conditions.
Since regulations change with some frequency, it is vital to consult both federal and local regulations.
