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.

Asbestos and Health rsk

Asbestos is not a single substances but a group of silicate minerals that are highly fibrous.As it is a part of construction .It is important have the knowledge on asbestos and the risk associated with it when worker are exposed to it.The fibers which are too small to be be visible and heat resistant and strong and flexible enough to be woven.The durability of fibers becomes a problem when they get in to lungs tissue where they can remain for a long time.Most people who have developed asbestos at work.Jobs in which asbestos may be encountered are found in many areas including mining,construction,automotive repair,manufacturing,shipyards ,steelmits etc.However asbestos is naturally occurring minerals and when found in nature.

General prequations (PILING)

Men handling piles or working o piling operations should always wear safety helmets,safety shoes, safety glases, stout gloves and be equiped with ear protection. At the start of each shift hammers and extractors should be carefully checked for loose bolts etc. All other equipment should be inspected daily for defects. Piling operation should be under taken except under competent supervision and with a crew experienced in this class of work. Piling operation are construction process with special hazards. In addition to this special hazard men are exposed to the hazards commonly associated with all type of construction work ,and precautions against these general hazards must not be neglected.

Piling operation

Piling operatin may be the first work which will be carried outbin the construction sites.the risk associated with this work is high.It is neccessary to  review the current safety arrangements and working procedures to ensure a safe work process.The situation which necessitate pile function for a structures are : The structure is very heavy. *An excavation for foundation is impracticable. *Problem of sub soil water in the foundation trench. *The geological conditions found on the site. *Need of  a special desighns ,such as resistence to ship impact for bridge piles. *Special friction or standard required relating to the construction.
