FAQ's

What kinds of dangers do High Pressure signs warn us about?

High Pressure signs are important because they tell us about high pressure systems that can be really dangerous. These systems can release a lot of energy quickly and cause serious harm. Things like pipes, broken hydraulic lines and ruptured pressurized vessels can all cause bad injuries. High Pressure signs let workers know that these systems are around before they start working with them.

Where should we put up High Pressure signs?

We should put these signs on things like pressurized vessels and tanks, hydraulic and pneumatic lines, compressor equipment and high-pressure steam systems. We should also put them near pressure relief valves and at the entrance to any area where pressurized systems are used. The sign should be easy to see from a distance.

What are the rules from OSHA that apply to high-pressure dangers?

There are rules from OSHA that apply to systems. For example, OSHA 29 CFR 1910.147 is about controlling energy when we are working on these systems. OSHA 29 CFR 1910.217 is about systems on mechanical power presses. Osha 29 CFR 1910.169 is about air receivers for boilers and pressure vessels. There are also standards from the ASME Boiler and Pressure Vessel Code that people often follow for pressure equipment safety.

Do we need High Pressure signs on equipment that already has gauges and pressure indicators?

Yes, we do need High Pressure signs on this equipment. Gauges tell informed workers what the pressure is. High Pressure signs tell all workers, no matter how much experience they have with the high pressure systems.

Do High Pressure signs apply to both hydraulic and pneumatic systems?

Yes, they do. Both kinds of systems can be very dangerous. Hydraulic systems can release fluid at high pressure, which can hurt people. Pneumatic systems can whip around violently if a line disconnects. High Pressure signs are important for both kinds of systems.

Should High Pressure signs say what the pressure level is?

For general area warnings, specifying pressure is not always required on the sign itself. In some situations it is very important for maintenance workers to know the pressure level so it can be helpful to add it to the sign or put up a separate sign with the pressure information.

What size options are available?

The signs come in different sizes. Some common sizes for hazard signs are 3.5" x 5", 5" x 7", 7" x 10", 10" x 14" These sizes ensure that the signs are visible and easy to read. These signs need to be big enough to grab people's attention and small enough to fit in the space available.
