1 .1 Safe Working Environment

2 Safe Place of Work Common Law Duty Reasonable care to protect employees from foreseeable injury Wilsons and Clyde Coal Co. v English Safe place of work SSOW Safe plant and appliances Safe and competent workers Fulfill duty though regular inspection

3 Safe Place of Work Statutory Duty HASAWA AFAIRP WHSWR Further clarified

4 Safe Place of Work Practical considerations Where Each area has own hazards What Tasks Environment Temp, light, ventilation, waste, floors Space Ergonomics Traffic routes Maintain std s

5 Safe Access / Egress Clearly marked gangways Walk routes Maintenance of floors, stairs Traffic routes Doors, gates Emergency egress Disabled workers provisions Maintain std s Critical Interface between pedestrians and traffic segregation

6 Slip Resistant Surfaces For safe movement of people Mats at entrances Designated walkways Stairs, steps, ladders, footholds to vehicles Ramps, slopes Where liquid spills are likely Maintenance access areas Exposed to weather Grime, slippery growth

7 Slip Resistant Surfaces Consider Consequences of slips Tasks, tools Contamination spills Drainage to control spills Level of use of surface Frequency Environmental issues Footwear requirements / control Slip resistance rating

8 Wet Coefficient of Friction COF Friction between two surfaces µ = R / F µ = coefficient of friction R = normal reaction force F = friction force Roughness Interlocking of surfaces, requires force to overcome it Molecular adhesion Wet rubber etc more µ than dry

9 Wet Coefficient of Friction COF Wet COF Two surfaces separated by liquid Can lead to molecular adhesion Also lead to reduced COF slippery surface So Consider contaminants, surface, material (footwear) Establish wet COF

10 Slip Resistant Testing Surfaces and Footwear Pendulum COF Test Pendulum swings over surface in controlled manner Pendulum = rubber slider Slipperiness value = PTV Pendulum test value 0-24 = high slip potential = moderate 36+ = low

11 Slip Resistant Testing Surfaces and Footwear Micro roughness meter Value = RZ Slip potential of surface -10µm = high slip potential 10-20µm = moderate 20+µm = low

12 Slip Resistant Testing HSE Slip Assessment Tool SAT Measurement and analysis of resistance measurements RZ factor used to guide selection of work and walk surfaces Select high RZ where contaminants likely Balance with need to clean High RZ may be difficult to clean

13 Slip Resistant Testing Effects of contaminants Contact pressure Size / shape of contact area Velocity of movement Viscosity of liquid Liquid contaminant can fill in peaks and troughs of surface Acts as lubricant Reduce COF Can lead to aquaplaning Dry contaminants can also cause reduced COF

14 Wet cleaning Cleaning of Floors Suitable footwear, slip resistant relative to surface Sweep floor Prevent waling on until dry Barriers, cones, signs Correct balance of cleaning solution to water Change water when dirty, mop floor Leave solution on floor for few minutes to loosen dirt and grease Gently scrub with brush Squeegee dry or mop Final mop over Dry mop / squeegee

15 Cleaning of Floors Machine cleaning Steam cleaning Penetrates deep into flooring Mobilises any grease Leaves floors almost dry Some machines recover dirty water Scrubber Clean into grain of floor Use correct settings, solutions, maintenance Different brushes Leave floor dry

16 Cleaning of Floors Footwear Not as simple as selecting slip resistant from brochure Needs to match surface and contaminants from cleaning Softer sole, close tread pattern good for fluid contaminants and indoor work Open tread pattern better for outdoors or solid contaminants oil resistant not oil slip resistant Means not damaged by oil

17 Good Housekeeping A place for everything and everything in it s place Procedures Prevent spread of contaminants Reduces slips, trips, falls Reduces chances of fire careless storage of flammable waste Dust exposure health problems. Also fire hazard Keep damp to prevent becoming airborne Wet before sweeping or vacuuming
