HEALTH AND SAFETY PRODUCTS
GUIDELINES
SAFETY DO’S & DON’TS
The do’s & don’ts listed below are by no means fully exhaustive, you should also refer to the current issue of the Precast
Flooring Federation Code of Practice available on Tel: 0116 253 6161.
Health and Safety is a major concern for Bison, and we have developed a range of methods and systems which help to
ensure that anyone using Bison products can do so with minimal risk to themselves or others.
•
Do not alter the product without written permission from Bison Design Office, altering the product may compromise
its structural integrity and lead to failure. This includes notching, hole forming, shortening, narrowing the unit etc.
•
Do not alter the product in-situ, any permissible alterations must be completed on a flat stable platform. i.e. on the
ground or floor area.
•
Do not allow anyone to walk or work beneath the product whilst it is being hoisted or suspended.
•
Do not work in areas without the appropriate perimeter edge protection, handrails, guardrails, platforms or stages.
•
Do not access working areas without properly constructed, maintained, secured and illuminated, stairways, ramps,
ladders or the like.
•
Where lifting hooks are specified within a contract, do hoist the units by crane using ALL the lifting points in the top
surface provided for that purpose. Prior to lifting safety chains must be loosely slung around the underside of the
unit. The safety chains may only be released immediately before the slab is placed in its final position.
•
For insurance purposes, Bison do not supply or hire lifters or chain sets. Please refer to our information sheets for
details of supplier hire or purchase.
•
Do not run plant or store equipment on the precast floor before it is grouted and cured. Once cured do not exceed
the loads specified by the engineer.
•
Do use a passive fall protection system wherever reasonably practicable considering all heights where the potential
fall distance could result in an injury.
•
Do ensure the perimeter scaffolding is positioned no more than 900mm below the top surface of the flooring, or landing level.
•
Do ensure all voids created whilst placing units are adequately protected during and after erection.
•
Do ensure all brickwork, blockwork or concrete is adequately cured, stable and fit to receive precast concrete units,
and that steelwork is stable.
•
Do ensure the stability of support beams, lintels etc. is considered, particularly the rotation of support member due
to unequal loading.

Trailasafe®
Trailasafe® is designed to prevent or mitigate injuries
resulting from falls from trailer decks. Comprising
synthetic mesh suspended from a series of brackets
housing support arms, the system arrests the fall of
personnel, absorbing the energy of their descent and
ensuring their safety. Fully demountable, the system can
be stored within the vehicle or at the unloading point.
THE BISON AIR MAT
The Bison Air Mat system has been tested by the BRE
and approved by the HSE. The Bison Air Mat system
comprises a series of interconnected and interlinked
mats available in a wide range of standard sizes. Using
a combination of modules they will accommodate
almost any floor area. Where the edges of an area to be
protected are open, or have large vertical voids that may
pose the hazard of “roll-off” fall to a lower area, special

NOTE; Due to the principle constituents of cement, the liquid released whilst drilling drainage points etc is likely to
have a caustic effect on the eyes and skin. For further information or to obtain the latest issue COSHH data sheet for

The yellow, anti-slip cover is fully reusable and comes in
two sizes, 250mm or 350mm square. Each may be either
screwed down or fitted without the need for power tools,
