Frequently Asked Questions - Safety
  • What confined space entry equipment do I need to comply with OSHA regulations?
    View answer
    • First of all, the air quality in the confined space will need to be monitored and checked for harmful gasses. You can do this with one of the gas detectors sold by USA BlueBook. If the air quality is found to be harmful, the area can be purged or ventilated to provide fresh air. This can be done with a confined space blower. A self-contained breathing apparatus can also be worn while entering the confined space for added reassurance. The air quality in a confined space can change very quickly, so the air must be monitored at all times.
      Next, you need a means for lowering or raising someone out of the confined space. A man-rated tripod or davit arm is used for this purpose. The person entering the confined space is referred to as the entrant. He will need a full body harness that will attach to a cable hook from the tripod or davit arm winch. The entrant will stay hooked up to this cable at all times while in the confined space. If the confined space does not have room for a ladder for the entrant to climb down into, a back-up fall protection device is needed. A rope grab is an effective inexpensive device for this. Also, for the safety of the entrant, a person needs to be posted by the winch on the outside of the confined space. This person is called the attendant. The attendant will need to have a constant line of communication with the entrant. In the event of an emergency, the attendant can raise the entrant with the winch.
      We recommend that appropriate training from an OSHA certified trainer be conducted prior to entering a confined space. Also, we offer several manuals on correct confined space entry.
  • Does the cage come with the DBI Ladder Safety system?
    View answer
    • The system comes with a top bracket assembly, bottom bracket assembly, a cable guide and 3/8" cable based on the system length. The cage is not included.
  • Do you carry Class I or intrinsically safe two-way radios?
    View answer
    • Class I or intrinsically safe means explosion proof, which we do not carry at this time.
  • Can I get keyed alike locks for my Lockout Station?
    View answer
    • Yes, although we do not recommend keyed alike locks for safety and compliance reasons.
  • Can you get single gas detector as we do not need one that detects four gasses?
    View answer
    • Yes, single gas detectors are available. Please call us first with your application information to determine if single gas detection is the right solution for you.
  • Are there different size facemasks available for the SCBA units?
    View answer
    • There are different sizes available, and the facemask that comes with the unit is adjustable.
  • Are the spreaders listed in the shoring section able to be used with any brand of shoring box?
    View answer
    • We do not recommend interchanging parts between manufacturers of shoring systems. This is due to safety and compliance considerations.
  • Can I get signs that are not listed in your catalog?
    View answer
    • Yes, in most cases, other signs and custom signs are available. These generally have about a two week lead time. Please call us for a quote.
  • How often should sensors be changed in my hand held gas detector?
    View answer
    • Most sensors are warrantied for two years by the manufacturer. Some will work longer than that, however, we recommend that they be bump tested before going into a confined space. This is especially true if they have been sitting on a shelf for a while. The gas detector will also give you an error message if the sensor is bad.
  • Do you carry respirators with cartridges rated for asbestos?
    View answer
    • No, we do not and our vendors recommend using a SCBA unit around asbestos at the minimum. Asbestos is very dangerous to work around and should not be taken lightly.
