The Code reproduces the practical requirements in the Regulations for the work environment. So far as is reasonably practicable, the layout of the workplace must allow people to enter and exit safely and move within it safely under normal conditions and in an emergency. Work areas must have space for work to be carried out safely. Floors and other surfaces must be designed, installed and maintained so work can be carried out safely. Lighting must enable safe work, safe movement and safe evacuation. Ventilation must enable workers to carry out work without risk to health and safety. Workers exposed to extremes of heat or cold must be able to carry out work without risk to health and safety. The extract also states that work in relation to or near essential services such as gas, electricity, water, sewerage and telecommunications must not affect the health and safety of persons at the workplace.
On entry and exit, the Code says the means of entry and exit to and from the workplace must be safe. This may include ensuring that workers with special needs or disabilities can safely enter and leave the workplace. Entries and exits should be slip-resistant under wet and dry conditions. Aisles and walkways should be at least 600 mm wide and kept free of furniture or other obstructions at all times. Where it is necessary to clearly define routes, the boundaries should be marked by a permanent contrasting line at least 50 mm wide or by glowing markers. Entry and exit routes, stairs and walkways should be adequately lit.
The Code also gives practical guidance on stairs, doors and traffic routes. Open sides of staircases should be guarded with an upper rail at 900 mm or higher and a lower rail. A handrail should be provided on at least one side of every staircase, with additional handrails where needed on wide staircases. Separate entries and exits for mobile equipment such as forklifts or trucks and pedestrians should be provided to minimise the risk of people being hit by moving vehicles. If people and vehicles have to share a traffic route, kerbs, barriers or clear markings should be used to designate a safe walkway. Doors and gates should be fitted with safety devices if necessary, and doors on main traffic routes should have a transparent viewing panel unless they are fire-rated doors.
On housekeeping, the Code says an untidy workplace can cause injuries, especially slips and trips, so good housekeeping practices are essential. Spills should be cleaned up immediately, walkways kept clear, work materials neatly stored and waste regularly removed. It also notes that good layout, sufficient storage space, worker training in housekeeping procedures, suitable waste containers and regular emptying all help keep the workplace tidy.
On work areas, the layout should provide sufficient clear space between furniture, fixtures and fittings so workers can move about freely without strain or injury and evacuate quickly in an emergency. In deciding how much space is needed, the Code says you should consider the physical actions needed to perform the task, whether workers need to move around while working, whether the task is seated or standing, access to workstations, the equipment handled and any personal protective equipment worn. Environmental factors including heat or noise may require more space, as may manual tasks or work using tools such as knives.
On floors and other surfaces, the Code says floor surfaces should be suitable for the work area. Floors should be inspected regularly and maintained to eliminate slip and trip hazards. Common examples include trailing cables, uneven edges, broken surfaces, gratings or covers, and loose mats or carpet tiles. Floor surfaces require sufficient grip to prevent slipping, especially in areas that may become wet or contaminated. Floors and any other surfaces people may walk on, such as mezzanines or platforms, must also be strong enough to support loads placed on them.
On workstations, the Code says it may be necessary to determine whether work is best carried out in a seated or standing position, or a combination of the two. Ideally there should be a mix of seated and standing tasks because neither prolonged sitting nor prolonged standing is desirable. Workers should be consulted when carrying out this assessment. Workstations should be designed so workers can work in a comfortable, upright position with shoulders relaxed and upper arms close to the body. Adjustable workstations are preferred where possible because different workers require different working heights. For seated work, seating should provide good body support, especially for the lower back, provide foot support, allow adequate leg clearance and freedom of movement, and be adjustable.
On lighting, sufficient lighting must be provided, whether from a natural or artificial source, to allow safe movement around the workplace and to allow workers to perform their job without awkward postures or eye strain. The Code says relevant factors include the nature of the work activity, the hazards and risks in the workplace, the work environment, illumination levels, the transition of natural light over the day, glare, contrast and reflections. Additional lighting may be needed for some work or at places of particular risk, such as crossing points on traffic routes. Emergency lighting must be provided for safe evacuation in an emergency.
On air quality, workplaces should be adequately ventilated. Fresh, clean air should be drawn from outside the workplace, uncontaminated by discharge from flues or other outlets, and circulated through the workplace. The Code discusses natural ventilation, mechanical ventilation and air-conditioning. It says an air-conditioning system should provide a comfortable environment in relation to air temperature, humidity and air movement, prevent excessive accumulation of odours, reduce respiratory by-products and other indoor contaminants, and supply fresh air while exhausting some stale air and filtering and recirculating some indoor air.
