Basic Safety Awareness Manual

Basic Safety Awareness APPLICATION OF SAFETY PRINCIPLES

Occupational Health & Safety Legislated Employee Induction

Module 1 Fundamentals of Safety 1. Definition of Safety Safety means free from hazard or threat which may lead to: a. Injury / Illness of person. b. Damage to property / Equipment. c. Loss of materials / Resources

2. What is an Incident? An Incident is an undesired / unplanned event that could result in: a. Injury / Illness b. Damage / Loss Incidents are caused by unsafe acts and unsafe conditions

Unsafe Acts May be defined as a departure from an accepted norm, or correct procedure or practice, an unnecessary exposure to a hazard, or conduct jeopardizing the degree of safety normally present.

Unsafe Conditions May be defined as any physical condition that, if left uncorrected, may lead to an incident.

The sources of Incidents There are four sources

1. People This element includes both employees and employers. It is said that people are responsible for more than 80% of incidents through unsafe acts.

2. Equipment By “Equipment” we mean anything used by the employee to carry out his work, ex, such as angle grinders, hoists, cranes, dumpers, etc.

3. Material The material person use, work with or make provides another major cause of incidents. Materials can be sharp, heavy, hot, toxic etc. 4. Environment Environment is usually associated with such items as lighting, noise levels, heat, cold dust fumes humidity, gases, water etc.

Injuries Injuries to workers are classified into “Fatal”, “Disabling”, “Non-Disabling” or “First Aid only” incident and includes cases where workers health is impaired through poor conditions in the workplace such as poor lighting ventilation, control of harmful dusts and vapours, vibrations, radiation etc.

Property Damage Incidents The property damage incidents is very important. In 1969 a study of industrial accidents was undertaken by F. Sird in America. The study of over 1,7 million industrial accidents reported by nearly 300 companies employing some 1,1 million employees revealed that for every “serious or disabling” injury reported, there are approximately ten injuries of less serious nature. Also for every single ”serious or disabling” injury there were approximately thirty incidents of property damage and 600 incidents with no visible injury or property damage (No less Incidents or “Near Misses”).

No Loss Incidents The bulks of incidents are experienced in this category and normally receives the least attention. These are however, as important as any of the other two categories mentioned above as the degree of loss or damage caused by any incident is normally fortunes and is usually the outcome of a set of circumstances coming together or not. If a person is standing next to a building and a brick falls from the top of the building it just depends on where the person is standing as to of it is a “Near miss”, “non disabling injury (if he is wearing a safety helmet) or a disabling injury (if he is not wearing a safety helmet and is standing where the brick falls).

Serious or Disabled Injury Minor Injuries Property Damage Incident with no visible Injury Or Damage The effects of incidents include PRODUCTION INTERRUPTON and PROFIT REDUCTION, so the accidental loss involves People – Property – Production – Profit. The effects may range from insignificant to major or catastrophic, from a scratch to a dent to multiple deaths or complete loss of plant (see sketch REAL COSTS OF ACCIDENTS). The above ratio can vary from 1: 3 to 1: 1000 depending on the sophistication of the operation. Unsafe Acts An employee might perform an unsafe act because of: 1. 2. 3. 4.

Lack of knowledge. Lack of ability. Incorrect attitude. Physical or mental defects.

Unsafe Acts are classified as: ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦

Operating without authority Failure to isolate or secure Operating at improper speed Making safety devices inoperative Using defective equipment Using equipment improperly Failure to use personal protective equipment Improper loading or placing Improper lifting Taking an unsafe position or posture Horseplay Drinking alcohol or taking drugs Etc.

Unsafe Conditions are classified as: ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦

Inadequate support Defective tools, equipment, or materials Inadequate working, storage and traveling space Fire and explosion hazards Poor housekeeping Hazardous atmospheric conditions, dust, gases, fumes and vapours Excessive noise Radiation exposure Inadequate illumination or ventilation No personal protective equipment Poor lighting Etc.

These unsafe conditions, aswell as being caused by personal factors, also result from: ♦ ♦ ♦ ♦ ♦

Poor standards Poor designs Misuse Normal wear and tear Incorrect equipment and tool

Unsafe conditions are also caused by persons not doing something they should, or doing something they should not.

Good Housekeeping Good Housekeeping is the cornerstone of any Safety Management Programme. Proper planning and a good layout facilitate good housekeeping, and this in turn, creates greater efficiency. Clean and clear working, stacking and storage areas can only improve production and prevent injury and loss incidents. Sites, factories, workshops and yards giving ongoing attention to such matters as tidiness, scrap and refuse removal systems, demarcation of roadways, aisles, storage areas and proper storage or stacking practices will benefit. This is because: 1. 2. 3. 4. 5. 6.

Time is saved. Material waste is reduced. Damage to plant and equipment is reduced. There is greater work output. Movement of vehicles and plant become easy. Fewer hazards are encountered.

No one likes working in a dirty, untidy or cramped situation. Regardless of the industry or operation. This makes the task extremely difficult and unpleasant, apart from inviting the obvious problems of fire risk. Stock control of stored material , theft etc. On site, for instance, if the timber, bricks and other materials are correctly stacked, the task of the person requiring such an item is considerably eased. Time is not waste in searching under a mound of haphazardly piled material for something, which may not be there. With good housekeeping there is less material and equipment damage. Remember: “GOOD HOUSEKEEPING MEANS A PLACE FOR EVERYTHING AND EVERYTHING IN IT’S PLACE”

Instruction No 3. 2. Knowledge Self Check No 3. Introduction: Mechanical hazards are one of the biggest contributors to the cause of injuries on a building site. It causes cuts, bruises, amputations, and fractures. It is fairly easy to discover most of the basic mechanical hazards by regular visual inspections and the elimination thereof is fairly simple. Machine Guarding Most machines have moving parts, which needs to be guarded to prevent persons from coming into contact with these moving parts and be injured. Drive belts, rotating shafts, cutters and cutting blades are some examples. Moving Machinery Maintenance and adjustments should never be carried out on machinery that is running or moving and machinery must be stopped and “locked out” before any repair or maintenance work is carried out. “Locked out” means that any electricity, steam, air pressure or anything else that drives the machine is diconnected or disabled so that the machine being worked upon cannot be accidentally started and so injure the person carrying out the work. Maintenance Mechanical equipment must be maintenanced and kept in good order to ensure efficient and smooth operation. Poorly maintained machinery will produce poor quality, place greater strain on the machine, the material and the operator and lead to early failure. Cutting edges must be kept sharp, moving parts must be well lubricated, air filters kept clean, loose parts with bolts and nuts and not tied with wire etc.

Inspection The operator of any machinery must be trained to inspect the machinery that he intends using daily before use. Inspections must include the checking of oil and water levels, air filters, drive belt tension, sharpness of blades, chisels, controls etc, as applicable. Hand Tools Hand tools must be kept in good condition. Mushroomed chisels must be ground down and chisel cutting edges kept sharp. Hammer handles must be without cracks or splinters fixed with correct wedges, where applicable and no welded galvanized piping used as handles. Files must be provided with handles and screwdriver handles must be tight. The bits of screwdrivers must be square and sharp. Pick handles must be splinter free and fitted properly so that it will not slide down onto the workers hands of fly off the end. Ladders Ladders must be inspected by the use before use and any defects rectified immediately. Knowledge Yourself Directions 1. Evaluate your work by answering the following items. 2.

Module 4 Electrical Safety Learning Activities 1. Read the Instruction Sheet No 4 describing electrical safety. 2. When completed evaluate your work using Self-Check No 4. 3. Proceed to Learning Objective No 5. Resources 1. Instruction Sheet No 4. 2. Knowledge Self Check No 4. Introduction: Unlike many other hazards, which can be seen or heard, there is no advance warning of danger from electricity, AND ELECTRICITY CAN KILL. Averages of one in thirty of all electrical accidents are fatal. Electric shock is a major hazard. The severity of the shock will depend on the level of current and the length of time it is in contact with the body. At very low levels of current the effect may only be an unpleasant tingling sensation, but this may be enough to cause a man to lose his balance and fall. Higher levels of shock can cause fibrillation of the heart, which is almost always fatal. An electric shock can also cause burning of the skin at the point of contact. Electricity on sites should always be treated with the utmost care. Electrical installations should be under the supervision and control of an experienced and competent person. Cables, Plugs and sockets ♦ Check that all cables are insulated, and undamaged. Do not allow cables to lie across pathways or come in contact with sharp edges or hot objects. ♦ Check that plugs and sockets are in good sound condition, and that the correct plugs are fitted and the wires are connected correctly, (Brown to live, blue to neutral and yellow to earth). ♦ The earth wire must be connected! ♦ If the cables are buried, they should be least 450mm below the surface and covered.

♦ If the cables are suspended, they should be at least 5 meters above ground level and properly supported. Power Tools ♦ Do not plug or connect power tools to light circuits. ♦ Power tools should be of double insulated type, a square on the casing will indicate this. ♦ Never carry a portable electric tool by its cable or lower it to the ground by its cable. ♦ Do not stop or start a portable electric tool under load. ♦ Make sure that all electrical equipment is undamaged before it is plugged in. ♦ Power tools must be checked regularly by an electrician. Lighting ♦ Always provide sufficient light for the job. ♦ Keep the bulb and shade clean. ♦ Always use the right globe for the light fitting. ♦ Keep any windows clean. ♦ Lighting supply lines must have an earth wire included and connected. General ♦ Ensure tat earth leakage protection devices are operating correctly. ♦ Keep electrical cables, fittings, tools, etc dry and away from water. ♦ Keep distribution boards cover plates and doors in position and closed. ♦ So not connect extension leads without the correct plugs.
