What are the health and safety considerations for waste management?
Waste and recycling has one of the highest rates of fatal and major injuries of any UK industry. The causes are consistent: vehicles and mobile plant moving around people, contact with machinery during clearing and maintenance, fires in stored waste, slips and falls, and exposure to dust, bioaerosols and hazardous substances. The industry body, the Waste Industry Safety and Health (WISH) Forum, publishes guidance that sets the benchmark for most of these risks.
Workplace transport on waste sites
Being struck by a moving vehicle is the most common cause of death in the waste industry. Yards combine refuse collection vehicles, loading shovels, forklifts, visitors' cars and pedestrians in tight spaces. Segregation, one way systems, reversing controls, visibility, banksmen where necessary and clear site rules for drivers and visitors are the core controls.
Plant, conveyors and machinery guarding
Recycling facilities are plant environments: conveyors, picking lines, magnets, trommels, balers and shredders. PUWER requires dangerous parts to be guarded and equipment to be maintained, and the most serious injuries happen when someone reaches in to clear a blockage. Isolation and lock off procedures that are quick enough to be followed, and supervised, are essential.
Fires in waste
Stored waste catches fire easily and burns for a long time. Fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005 has to deal with stockpile size and separation, hot loads, lithium batteries in the waste stream, detection and firefighting water. Most sites in England that store combustible waste under an environmental permit also need a fire prevention plan approved by the Environment Agency.
Rendering, hydrogen sulphide and explosive atmospheres
Rendering processes animal by-products, including fallen stock and material from veterinary work. Decomposing material can release hydrogen sulphide, which is toxic and can deaden the sense of smell at dangerous concentrations, and some processes create explosive atmospheres covered by DSEAR. Pits, tanks and drains may be confined spaces. We assess these processes as they actually run, from working in them.
Energy from waste and incineration
Energy from waste plants combine the hazards of waste handling with those of a power station: bunkers and cranes, boilers, high temperature plant, ash handling and outage work by contractors. Permit to work systems, confined space entry and contractor control are central.
Dust, bioaerosols, sharps and COSHH
Handling waste exposes workers to dust, bioaerosols from organic material, and sometimes needles and other sharps on picking lines. COSHH assessments, respiratory protection, hygiene facilities, vaccination where appropriate and needlestick procedures all form part of a sound system.
Noise, vibration, odour and traffic around the fence
Noise and vibration from plant affect workers and neighbours alike. Odour and vehicle movements are where waste operations meet their regulators and the local community. Building them into the management system, rather than leaving them to the complaints file, protects the permit and the workforce.
What are the legal requirements for waste management?
Waste businesses carry two sets of duties. Health and safety law, enforced by HSE, covers the protection of workers and others. Environmental law covers the waste itself, including the duty of care under section 34 of the Environmental Protection Act 1990 to store, transfer and dispose of waste properly, and the conditions of the site's environmental permit. We focus on the health and safety side and make sure it fits with the permit conditions.
