Walking surfaces

Deck plank vinyl profiles or composite boards are used to form the base of the walking surfaces or stairs.

The oudet of the tail pipe shown in Figure 6.31 is far too near the walking deck (almost under the walking surface). It would be inadvisable to walk on this deck when this SRV goes off. When discharging, it will blow against the deck, which can possibly create built-up backpressure. ... 

There is a common perception, but not supported by building code documents (or supported by some outdated documents) that the coefficient of friction for any materials made for walking surfaces should be not less than 0.50, in order to be safe. Not all WPC deckboards would satisfy this (unofficial) criterion.

I recall the case of a miner who was working in an underground area where there was no illumination. The only source of light was from his cap lamp. The walking surface was full of mud and covered with a layer of muddy water. One day, while walking down this drift, he stepped into an 18-inch hole hidden by the muddy water, twisted his ankle, and fell to the ground in pain. Despite his immense pain, he continued to work for the next 6 hours until he collapsed in agony and called for help.

Any physical state that deviates from that which is acceptable, normal, or correct in terms of its past production or potential future production of personal injury or damage to property any physical state that results in a reduction in the degree of safety normally present. It should be noted that incidents are invariably preceded by unsafe acts and/or unsafe conditions. Thus, unsafe acts or unsafe conditions are essential to the existence or occurrence of an incident. Some examples of unsafe conditions include defective hand tools, uneven or slippery walking surfaces, faulty electrical wiring improper storage of flammable or other hazardous materials, and unguarded machinery. 

Static coefficient of friction (SCOF) relates to the traction between a person s foot or shoe sole and the walking surface. We can define SCOE as the relative force that resists the tendency of the shoe or foot to slide along a walkway surface. ADA reconunends a minimum of 0.6 on level walking surfaces and 0.8 on ramps. OSHA requires an SCOF 0.5 in all areas. Slip resistance relates to a combination of factors including type of surface, and care and maintenance procedures with the presence of foreign materials between the foot/shoe sole and the walking surface. The AIA s Academy of Architecture for Healthcare states that floor materials shall be readily cleanable and appropriate for each location. Install water-resistant floors in all food preparation areas and in locations containing baths or showers. 

Controls One control for preventing slipping conditions involves inspection. Work planning should include inspection of working and walking surfaces to remove or prevent slip hazards. 

Mechanical power transmission equipment that is out of reach of people may not require guards. Various standards set the minimum distance required from a floor or walking surface to overhead mechanical power transmission apparatus. The minimum distance is often about 8 ft. Most people would not be likely to contact or reach above this distance. Anthropometric reach data can also establish safe distances from people to danger points. Distances to danger points within reach require guarding. There may be overhead or enclosing screens, walls or fences that create safe locations. These barriers must be permanent and substantial. Only trained workers should have access to the enclosed locations. 

Texture The texture of a surface can also lead to visual errors and accidents. For example, a textured pattern in a carpet that continues from a floor to stairs can create an illusion. Someone looking at the floor may not detect where the stairs begins, may mis-step and faU. It is better to use non-texture finishes on stairs and certain walking surfaces. A change in finish may help someone see that the change reflects a change in elevation or a potential tripping hazard.

Friction is the resistance between things, such as between work shoes and a walking surface. Without friction, workers are likely to slip and fall. Probably fhe best example of this phenomenon is slipping on ice. On icy surfaces, shoes can t grip the surface normally, causing a loss of traction and a fall.
