- Fix It. If you discover a weakened or missing rail section, upright or toe board, correct the situation if you can.
- Report it. If you can’t immediately correct the situation, report it to someone who can so that the hazard can be eliminated
- Check It. If you bump a rail with material or equipment, check back to see if it is weakened and then fix or report any needed repairs.
- Once the wall form work platform is constructed, ladders or other approved methods such as ramps, stairways, or the building floor must be used to access it. If the elevation change is greater than 19″ when stepping from the floor to the work platform, install a step for safe access.
- Workers are not permitted to climb the form or rebar to gain access to a wall form work platform. It makes no difference that a worker is tied-off during the climbing process. The hazard with 100% tie-off while climbing the form to access a work platform involves the positions workers are in as they attempt to climb on and off the work platform. In addition, the vertical form itself does not have the same climbing characteristics as a ladder.
- Climbing the vertical face of the wall form is permitted only when work is performed on the form (i.e., when installing or removing taper-ties). There is normally no other way to accomplish these work tasks. However, in the case of accessing work platforms, other methods are available. Make sure walls are braced before climbing.
- When performing work off a work platform, fall protection is required if your feet are 6′ or more above a lower level. This is typically provided through the use of guardrails on the back side of the working platform and ensuring the platform is at least 39″ below the top of the form. If this is not feasible, there are a few options available:
- Install a 2nd working platform, complete with guardrails, on the opposite side of the wall form.
- Install a guardrail system at the standard 21″ (midrail) and 42″ (top rail) heights on the opposite side of the wall form.
- Practice 100% fall protection using retractable lanyards. (This is the last resort to be used only if nothing else is feasible.) Anchorage point for 6′ shock absorbing lanyards must be 18.5′ from the lower level and 14.5′ for retractable lanyards.
- General requirements (number of spaces, number of floors, size of site)
- Structural systems (precast, cast-in-place, steel)
- Architectural (brick finish, formalizer, etc)
- Site challenges
Our third and final post in our It’s Electrifying series focuses on electrical cord maintenance. Follow these inspection tips to ensure electrical cords are safe to use.
- Only 3-prong extension cords with correct rating may be used.
- Check your cords rating AND the equipment’s amps to ensure the cord is compatible with the equipment.
- Tools and cords should be inspected on a regular basis to ensure everyone’s safety. Questions to ask during inspection include:
- Is there any insulation showing?
- Is there any twisting of the wire inside the extension cord?
- Is there proper strain relief?
- Is the cord wired correctly?
- Damaged cords or cords showing insulation should be removed from service and tagged, “DO NOT USE”
- Tools or cords tagged “DO NOT USE” should be repaired or disposed of immediately.
- Flexible cords should always be used in continuous lengths without splicing or taping. This means NO ELECTRICAL TAPE should ever be used to splice two lengths together.
- Hard service flexible cords No. 12 or larger may be repaired, if repaired by a designated Competent Person and the cord is repaired back to original quality.
Taking a few extra moments to inspect the cords on your job site or at home may just save a life.
