OPERATION

When the platform reaches the top, and #3 pivot bracket goes over the top of the rails, the discharge gate opens

and dumps the material into waiting wheelbarrow or spreader.

Safety hazards are not always obvious to workers. Unlike exposure to health hazards, where illness or injuries develop

slowly, safety hazards usually result in immediate injury or death.

Broken bones, cut, bruises, sprains, burns and loss of limbs, eyesight and hearing are the kinds of injuries caused by safety

hazards.

The rate of occupational injuries in roofing, in fact, ranks in the top ten of all major occupational groups.

Falls are the number one cause of serious injury and death to roofers. An estimated 10 percent of all roofing accidents

result from falls off roof edges, through roofing openings or off ladders, more than half of the non-fatal accidents result in

serious injury.

Unprotected and unguarded roof edges and roof openings create extremely hazardous conditions.

Ladders with cracked, loose or missing steps: with side rails broken or cracked and not attached firmly to the steps; with

broken, loose or missing locks, or coated with grease, oils or hardened bitumen can lead to serious injury. Ladders should

be inspected to make sure they're properly maintained and constructed and that they're long enough to extend three feet

above the roof's surface.

Improperly balanced or unstable hoists overturn and will often carry the worker along. Rolls of roofing felt should never

be used as counterweight. Workers should know the load capacity; it should be posted.

Skin contact with hot asphalt and hot coal tar pitch usually results in second and third degree burns. They usually involve

Kettle splashes from dropping pieces of coal pitch or asphalt into the kettle



Slips and trips while carrying hot bitumen in open containers



Splashes involving transfer operations like from the hot pipe outlet to a hot lugger, from a hot lugger to a

mop cart or a pail, or from the kettle to a pail

Sprains and strains, a majority of which involve the back, are the most common roofing injury and one of the most severe.

Almost 30 percent of these injuries result in 10 or more days away from work.

Two conditions must be met in order for fires and explosions to occur. First, there must be an ignition source, a welding

arc, spark, cigarette, flame or simply a hot spot as in a kettle or tanker. Secondly, there must be the right mixture of
