BET2492/BPS3413 CONSTRUCTION SAFETY Lecture 10 : Work Equipment Hazard and Control

LEARNING OUTCOMES Upon completion of the class, it is expected that student will be able to: LO1: Identify hazards on work equipment LO2: Determine suitable controls when using work equipment

INTRODUCTION Any equipment used by an employee at work is generally covered by the term ‘Work Equipment’ Examples: hand tools, power tools, ladders, photocopiers, site plant, lifting equipment, fork lift trucks, and motor vehicles (which are not privately owned) Employers and the self-employed must ensure that work equipment is suitable; maintained; inspected; provided with adequate information and instruction; and only used by people who have received sufficient training.

SUITABILITY OF WORK The user must check that the machine is safe before it is used User has to check that the equipment complies with all the ‘supply’ law that is relevant

USE AND MAINTENANCE OF EQUIPMENT WITH SPECIFIC RISKS Some pieces of work equipment involve specific risks to health and safety Example: bench-mounted circular saw or an abrasive wheel Adopt hierarchy of control: eliminating the risks or, if this is not possible taking physical measures to control the risks such as guards, but if the risks cannot be adequately controlled taking appropriate measures, such as a safe system of work.

INFORMATION, INSTRUCTION AND TRAINING The information and instructions are likely to come from the manufacturer in the form of operating and maintenance manuals Should cover: all safety and health aspects any limitations on the use of the equipment any foreseeable problems that could occur safe methods to deal with the problems any relevant experience with the equipment that would reduce the risks or help others to work more safely, should be recorded and circulated to everyone concerned.

MAINTENANCE AND INSPECTION Work equipment needs to be properly maintained so that it continues to operate safely High speed, high hazard machines, which are heavily used in an adverse environment like salt water, may require very frequent maintenance Need to be done by competent and well-trained maintenance people

HAND-HELD TOOLS Work equipment includes hand tools and hand- held power tools These tools need to be correct for the task, well maintained and properly used

HAND-HELD TOOLS Hazards from the misuse or poor maintenance of hand tools include: splayed spanners that slip and damage hands or faces chipped or loose hammer heads that fly off or slip broken handles on files/chisels/screwdrivers/ hammers which can cause cut hands or hammer heads to fly off incorrectly sharpened chisels that slip and cut hands flying particles that damage eyes from breaking up stone or concrete incorrect use of knives, saws and chisels electrocution or burns by using incorrect or damaged tools for electrical work tools that slip causing stab wounds poor quality uncomfortable handles that damage hands use of poorly insulated tools for hot work in catering or food industry

MECHANICAL MACHINERY HAZARDS

MECHANICAL MACHINERY HAZARDS

IMPACT OF MECHANICAL HAZARDS A person may be injured at machinery as a result of: a drawing-in or trapping hazard such as between in-running gear wheels or rollers or between belts and pulley drives a crushing hazard through being trapped between a moving part of a machine and a fixed structure an impact hazard when a moving part directly strikes a person, such as with the accidental movement of a robot’s working arm a shearing hazard which traps part of the body, typically a hand or fingers, between moving and fixed parts of the machine a stabbing or puncture hazard through ejection of particles from a machine a cutting or severing hazard through contact with a cutting edge, such as a band saw or rotating cutting disc contact with a friction or abrasion hazard, for example, on grinding wheels or sanding machines entanglement hazard with the machinery which grips loose clothing, hair or working material, such as
