HAZARD AWARENESS Identify unsafe acts and conditions • An unsafe act is something that a person habitually does that may result in an accident. • An unsafe condition is something about the physical environment that may present a danger. Determine the corrective actions • Safety shall take corrective action to eliminate the cause of nonconformities in order to prevent recurrence. Corrective action, and the response time to initiate such actions, shall be appropriate to the consequences of the nonconformities. Implement corrective actions • Administrative (through personnel, management, monitoring, limiting worker exposure, measuring performance, training and education, housekeeping and maintenance.) • Engineering (isolation of source, lockout procedure, design, process or procedural changes, monitoring and warning equipment, chemical or material substitution.) • PPE (body protection, fall protection.)

Common Workplace Hazards Fire and preventions Safety in Lifting Operations Machinery Safety Working at Heights Chemical Safety Electrical Safety Office
Fire • combustible materials used for partitions, fixtures and furniture increase the fire loading in the premises. Due to the lack of proper maintenance and carelessness of staff, fire would be easily occurred. • common causes of fire • smoking materials left unattended • use of flammable liquid and dangerous substances • electrical fire due to short circuit or overloading of electrical apparatuses • mishandling or naked flame (e.g. lighters, matches,candles etc) • arson • obstruction in means of escape
Fire • Fire prevention • smoking materials • use of electrical equipment • use of flammable liquids • good housekeeping • maintenance of Fire Services Installation and Equipment (FSI)
Safety in Lifting operation • Life appliance • crab, winch, teagle, pulley block, crane, sheerlegs, excavators, pile driver, pile extractor, dragline, aerial ropeway, aerial cable-way transporter, overhead runaway • lifting gear • chain sling, ring, link, hook, plate clamp, shackle, swivel/eyebolt
Safety in Lifting operation • causes of lifting accidents • lack of training • poor maintenance • correct plant and equipment not available • misuse of plant and equipment • hurry to get the job done
Machinery Safety • Hazards associated with machines • traps • impact • contact • entanglement • ejection • Provision of effective machine layout • spacing • lighting • cables and pipes • ergonomics
Machinery Safety • machine layout • spacing : to facilitate access of operation, supervision, maintenance, adjustment and cleaning • lighting: general and local (for specific operations) • cable and pipes: to allow safe access and to avoid tripping, with sufficient headroom • ergonomics: provision of seating, correct placing of controls, positioning of operating stations and height of work tables
Working at Heights • works at height - definition • any person who is working at a level liable to fall a distance more than 2 meters • examples • fall of person due to collapse of scaffold or ladder • fall from height • fall from working platform, gangway, lift shaft and stairway • falling objects
Working at Heights • provision of suitable measures • safe use of scaffold • provision of working platform, gangways and runs • provision of guard rails • safe use of ladders • correct pitch (1 meter for every 4 m vertical height) • when locate in doorway, have a man to look after the bottom of the ladder • inspect ladder before use and regularly
Chemical Safety • Classification of dangerous substances • explosive • harmful • flammable • toxic • corrosive • oxidizing • irritant
Chemical Safety • Steps to reduce risk • labels on containers and receptacles • planning for chemical safety • identification of the hazard to be controlled • assessment of the risk • control of the risk • training of staff • monitoring the effectiveness of the strategy • necessary record-keeping
Electrical Safety • causes • damaged insulation • inadequate systems of work • inadequate over current protection (e.g.. fuse, CB) • inadequate earthing • carelessness • loose contacts and connectors • unprotect connectors • poor maintenance and testing • Hazards • electrical shock • arc eyes • ignition of combustible materials • overheating and damage to equipment • electrical explosion
Electrical Shock • Received when current passes through the body • Severity of the shock depends on: • Path of current through the body • Amount of current flowing through the body (Currents greater than 75 mA) • Length of time the body is in the circuit
Recognize the Hazards Stay at least 10 feet away from overhead lines
Office – Potential Risk in office • Visible Risk • Working with computer • Occupational Safety and Health (Display Screen Equipment) Regulation • Personal Health • Poor Working Condition • temperature, air quality, sound level, lighting • Invisible • Work pressure
Common Office Safety and Health Hazards What’s Wrong Here?
The following are important considerations when attempting to maintain neutral body postures while working at the computer workstation: • Hands, wrists, and forearms are straight, in-line and roughly parallel to the floor.Headis level, or bent slightly forward, forward facing, and balanced. Generally it is in-line with the torso. • Shoulders are relaxed and upper arms hang normally at the side of the body. • Elbows stay in close to the body and are bent between 90 and 120 degrees.

The following are important considerations when attempting to maintain neutral body postures while working at the computer workstation: • Feet are fully supported by floor or footrest. • Back is fully supported with appropriate lumbar support when sitting vertical or leaning back slightly. • Thighs and hips are supported by a well-padded seat and generally parallel to the floor. • Knees are about the same height as the hips with the feet slightly forward.
