Ladder storage

Ladder s are often thrown carelessly to the ground exposed to weather, rain and some times impact damage .Ladders supported horizontally  clear of the ground on a adequate number of supports.( Ladders over seven meters in length should have at least 3 point to avoid sagging) . Do not hang any ladder by its stiles from spikes fixed to a wall. Storage should be under cover as ladders Especially wooden which deteriorate faster when exposed to the effects of  weather. Particularly extreme of hot and cold ,we and dry .In case of metals ladders prolonged contact with water can cause rot.Wooden ladder should be stored in well ventilated situation away from radiators or hot pipes which can promote  warping.Aluminum alloy ladders should be kept away from wet lime of cement which can corrode.Tie rods ,hooks and fastening  are suspect able to corrosion in salt laden atmospheres.Do not hang anything on ladders that are in a stored condition.

Ladder safety

Anchor secure  the top of the ladder when the 3-4 foot extension is not possible. Place the ladder base 1/4 the height of the wall from the wall when using  a straight ladder. Use tool belts or land lines to carry objects.Climb and descend ladders cautiously. Face ladder and hold on with both hands. Carry tools on belts or raise and lower with hand line. Check shoes or rungs  for slippery surfaces. Do not lean out from the ladder if any direction.  If you have fear of heights don't claim ladder. Do not allow others to work under the ladder in use.  Always hold on with one hand and never reach too for to either side or rear to maintain balance. Never climb higher than second step from top on a step ladder or third from the top on a straight ladder. Never attempt to move,shift or extend ladder while in use.

safe use of ladder

Do not allow more than one person up a ladder at a time. Don't  use a ladder which is too short. Do not use defective ladder.  Do not use makeshift or  home made ladder. Do not overreach . Do not over load a ladder or support if with a rung bearing on a board.  Do not slide down  a ladder . Do not carry sheets of materials especially if it is winds. Do not use alloy or wet ladder near electrical conductors .  Do not extent the ladder 3-4 feet above the top support if used to access roof or other elevated surface. Anchor secure the top of the ladder when the 3-4 foot extension is not possible.

safe procedure to use ladder

Select the right ladder for job.Inspect ladder before you use it. Do  not create on slopping ground. Do not erect on movable object.Do not erect in front of a door that may be opened. Do not erect against a slippery surface. Do not erect on a shallow angle. Do not erect horizontally as a plank or bridge. Do not erect at too steep angle. Do not use tools or do jobs requiring two hands while standing on a ladder . Do not drop material from ladder. Do not straddle from the ladder for a near by foot hold.

Prequations in blasting operations

The building and area where abrasive blastng operations are taking place must have:  The area close sheeted so that the dust particle escape is is kept to a minimum.All windows protected to prevent egress or ingress of dust particle ;. All doors and other opening sealed with adhesive tape.All sanitary plumbing pipe work ,rain water pipes,electrical points protected. All open inlets to drains suitably covered or sealed to prevent ingress of girt to the drainage system.Any valuable features fully protected or where possible removed. The immediate  area fully barricade to prevent other persons including members of the public from gaining access.

Precuations (asbestose)

Storage: all asbestos meterials removed from or used on a job shall be stored in an approved container at all times.  Transportation : Approved container shall be used during the transportation of asbestos meterials.All such containers that contain asbestos shall be clearly marked " CAUTION :- HEALTH HAZARD CONTAIN ASBESTOS" SIGN SHALL BE POSTED AT ALL APPROCHES TO THE WORK AREA.Respirator  and protective overalls must be worn when entering this area.Asbestos handling carefully and use adequate clothing and respiratory equipment.

Health hazards

Asbestos fibre bundles can split with small fine fibers breaking away .If inhaled the boady is able to resist most of the large particles ,but fine fibers too small to see can ledge deep in the lungs. this can cause the following diseases:    Asbestosis : It is a formulation of scar tissue in the walls of the alveoli causing thickening and hence slowing the passage of oxygen in to the blood,this causing breathlessness on exertion   .Mesothelioma: It is a type of cancer of the lining around the lungs and  of the abdomen.   Lung cancer: It occures particularly amongest smokers exposed to asbestos. Fibers protecting the lungs are flattened after inhaling cigrette smoke ,so there is less protection againest asbestos fibre.
