General Work Safety

All Welding operators, Welders and shop personnel shall be trained on safe

operation.

Operators shall inspect machine before and after use for any defects.

Eye protection shall be worn at all times.

Always wear correct personal protective equipment (PPE) pertaining to the job

task.

Remove or secure jewelry, long hair, and loose clothing.

Avoid skin contact with metal and welded surface.

Remove all scraps of metal with a brush, NEVER by hand or with an air

compressor gun.

Always receive authorization before working with reactive or harmful emission

giving metals.

Welding Safety

When welding outside of a designated welding booth, ensure that a University hot

work permit is completed and adequate safeguards are in place to prevent fire and

personal injury. Avoid welding on materials such as galvanized or stainless steel in

order to minimize toxic fume exposure. Always utilize mechanical exhaust

ventilation while welding.

Arc Welding Safety

Make sure the work and /or work table is properly grounded.

Inspect your work area thoroughly before beginning. DOES NOT arc weld if it is

damp or substances have a potential to ignite.

Turn the arc welder off before removing any grounds from the table or material.

DO NOT arc weld with skin unprotected. The arc light acts as Ultraviolet light and

will cause something comparable to sunburn.

Avoid clothing that has pockets, or spaces where hot embers may fall into.

Welding Safety Eye Protection

There are many hazards associated with welding operations. In fact, over 25% of

welding mishaps are injuries to the eye(s). Arcing electricity produces three forms

of powerful radiation: infrared, visible light and ultraviolet. Each category presents

a unique set of hazards.

Infrared (IR)

Infrared energy, or heat, is low frequency energy that is not visible. Depending on

the wavelength, infrared light is most damaging to the surface of the eye (cornea)

and lens. Overheating of the lens leads to cataract formation (clouding of the lens).

Visible

Visible light is light that you can see. When you see the bright white welding arc

you are only sensing the visible light region (even though there is infrared and

ultraviolet light being emitted as well). This intense light can damage the sensing

area (retina) at the back of the eye.

Ultraviolet (UV)

Within the scope of welding, UV light is the most damaging radiation and isabsorbed primarily by the cornea. Eyes can be exposed to an enormous amount of

harmful UV light in a very short period of time through unprotected viewing of the

arc. Within seconds you can give your corneas severe burns without even knowing

it. The result is photokeratitis (more commonly referred to as Welders Flash or

Arc Eye). Symptoms usually flare up several hours after exposure.

Symptoms include light sensitivity, reddening and pain described as sandpaper

behind the eyelids. Fortunately, the eyes typically recover from this burn.

Due to the hazards listed above, a welders helmet must always be worn. Squinting

does not help. Many mistakenly believe that the shade number corresponds to the

UV factor; however, this is incorrect. All quality welding helmets have lenses that

provide 100% UV and IR protection, regardless of shade level. The shade is there

to dim the bright visible light of the arc to prevent retinal damage and promote

easier viewing of the welding work. It is important to wear safety glasses with side

shields underneath your helmet. This provides protection during grinding or other

common operations when the helmet is flipped up.

Housekeeping at Workplace

Effective housekeeping can eliminate some workplace hazards and help get a

job done safely and properly. Poor housekeeping can frequently contribute to

accidents by hiding hazards that cause injuries. If the sight of paper, debris, clutter

and spills is accepted as normal, then other more serious health and safety hazards

may be taken for granted.

Poor housekeeping can be a cause of accidents, such as:

tripping over loose objects on floors, stairs and platforms

being hit by falling objects

slipping on greasy, wet or dirty surfaces

striking against projecting, poorly stacked items or misplaced material

cutting, puncturing, or tearing the skin of hands or other parts of the body onprojecting nails, wire or steel strapping

To avoid these hazards, a workplace must "maintain" order throughout a workday.Although this effort requires a great deal of management and planning, the benefitsare many.

Effective housekeeping results in: reduced handling to ease the flow of materials

fewer tripping and slipping accidents in clutter-free and spill-free work areas anddecreased fire hazards

lower worker exposures to hazardous substances (e.g. dusts, vapours)

better control of tools and materials, including inventory and supplies

more efficient equipment cleanup and maintenance

better hygienic conditions leading to improved health

more effective use of space and improved morale

reduced property damage by improving preventive maintenance.

improved productivity (tools and materials will be easy to find).

A good housekeeping program identifies and assigns responsibilities for the

following:

clean up during the shift

day-to-day cleanup

waste disposal

removal of unused materials

inspection to ensure cleanup is complete.

SKIN PROTECTION

Occupational dermatitis is a common health problem within the constructionindustry. Potential causes include cement, pitch, tar, paints, varnishes, brick,stone

and plaster dust, mineral oils, organic solvents, thinners, petrol, and white spirit, toname but a few.

It most commonly affects the hands, forearms and legs, but in dust, mist

and/ofume form it can also affect the face, neck or chest, etc, (any exposed area ofthe body). Some types of dermatitis, if untreated, can result in cancer. Look for the hazard warning signs on substance containers. Avoid contact with potential causes so far as is reasonably practicable, wherecontact is unavoidable wear suitable PPE. Report any rashes, warts and/or skin complaints to the site manager, nurse orfamily doctor as soon as possible.

Discussion points:

Get first aid for any cuts and grazes and keep them covered. Keep your workplace clean. Keep your skin clean and use after wash cream. Use barrier creams where appropriate. Dont use abrasives or solvents to clean your skin. Dont wear oil contaminated clothes next to your skin. Dont let synthetic resins or glue harden on your skin. Dont work with irritant/allergic substances if you suffer from eczema or allergicrashes.

Regularly inspect your skin for any possible signs if in any doubt seek advicefrom a professional.

WORKING AT HEIGHTS

Falling from height is the major cause of fatalities in the constructionindustry.More than half of falls from a height of over 2 metres result in death

or serious injury. All such deaths and serious injuries are preventable.

Main points:

Can work at height be avoided and the risk eliminated?

people and materials), PPE and suitable training as applicable.

Any work above 2m requires guard-rails, intermediate guard-rails and toe-boards to be fitted.

Where impracticable to fit guard-rails, intermediate guard-rails and toe-boards (short duration) then personal suspension equipment/fall arrest

equipment must be utilized as required.

Discussion points: Access ladders must be secured and extend sufficiently beyond workingplatforms to allow for safe access/egress.

Where access ladders run for more than 9m then suitable intermediateplatforms must be provided.

Consider weather conditions wet, windy and/or icy conditions can have a

serious impact on safety at height. Ensure operatives are suitably trained and physically capable for tasksbeing undertaken.

If guard-rails, fragile surface covers, void protections, etc, are removed for

any reason then they must be replaced as soon as possible, and in theinterim should be physically guarded.

Use crawling boards/roof ladders where applicable.

Plan work at height to include safe access, edge protection (for
