GUARDS MISSING ON ELEVATOR EQUIPMENT
Guards on elevator equipment will be provided as required by the TSSA regulations in force at the time of registration. Equipment shall not present a risk of entanglement, pinching, shearing, crushing, abrasion, electrical shock or tripping. The machine guarding must be provided with certification by a Professional Engineer indicating that the machine guarding is compliant with the MOL requirements. All machine guarding installations must be provided with an appropriate TSSA submission and must be performed by a licensed elevator contractor.
One-Year - Work and Materials
Equipment not meeting the Acceptable Performance/Condition shall be repaired.
The TSSA has recommendations for guarding of elevator equipment in such a manner that proper maintenance is not impeded. Entanglement means exposure of limbs or clothing to being snagged by moving equipment, causing the worker to lose their balance and possibly be drawn into the moving element. The most common form of this exposure is found in a traction elevator machine room with ropes travelling over sheaves, or as found with high speed rotating shafts having exposed keys or other projections Pinching or Nipping means that components or equipment elements that through changing positions or rotation can pinch or nip a worker’s limbs, commonly fingers, or clothing Shearing refers to components that through accidental contact can actually cause the loss of body parts Crushing is similar to nipping but more destructive and damaging effects Abrasion refers to components such as moving ropes or belts whose operation can lead to cutting injuries when contact with exposed skin occurs Tripping is a common hazard in many machine rooms, given the location and positioning of operating equipment. Many components are mounted low to the machine room floor (i.e. governor or motor generator set), and can often cause a person to fall over, especially when backing up without being aware of equipment positioning Electrical Shock is injury caused by momentary contact with live, unprotected electrical circuitry or components. Incoming voltages in elevator controls can range from 208 VAC to 600 VAC, and many drive motors operate at either building incoming power or variations thereof (i.e., between 240 and 460 volts).
