Hazard elimination is a hazard control strategy based on completely removing a material or process causing a hazard.Elimination is the most effective of the five members of the hierarchy of hazard controls in protecting workers, and where possible should be implemented before all other control methods.
During excavation, shoring systems speed up excavation and provide safety for workers since trenches can be prone to collapse. In this case, shoring should not be confused with shielding. Shoring is designed to prevent collapse where shielding is only designed to protect workers when collapses occur.
Traditional formwork is fabricated using wood, but it can employ steel, glass fibre, reinforced plastics and other materials. [3] Formwork for beams takes the form of a box that is supported and propped in the correct position and level. The removal time for the formwork will vary with air temperature, humidity and consequent curing rate.
An employee should be assigned to inspect equipment to insure proper safety. Equipment should have lights and reflectors if intended for night use. The glass in the cab of the equipment must be safety glass in some countries. [74] [75] The equipment must be used for its intended task at all times on the job site to insure workers' safety.
The formwork stays in place after the concrete has cured and acts as axial and shear reinforcement, as well as serving to confine the concrete and prevent against environmental effects, such as corrosion and freeze-thaw cycles. Flexible formwork. In contrast to the rigid moulds described above, flexible formwork is a system that uses ...
Personal protective equipment (PPE) includes gloves, Nomex clothing, overalls, Tyvek suits, respirators, hard hats, safety glasses, high-visibility clothing, and safety footwear. PPE is often the most important means of controlling hazards in fields such as health care and asbestos removal.
Visually, this may be observed on all concrete surfaces through the presence of blowholes following formwork removal. This is a problem because the first line of defence of all structural elements against carbonatation, chlorides, frost and abrasion, is the cover zone. It is therefore imperative this region is durable.
Lockout Tagout hasp can accommodate up to 6 padlocks, can be used during group LOTO procedure. Lock out, tag out or lockout–tagout (LOTO) is a safety procedure used to ensure that dangerous equipment is properly shut off and not able to be started up again prior to the completion of maintenance or repair work.
