Hazards

The installation of wastewater pipework in kitchens, washrooms, and laundry areas presents several hazards. Workers may encounter slips, trips, and falls due to wet or uneven surfaces, particularly when working at height or in confined spaces. Manual handling of heavy pipes and equipment poses a risk of musculoskeletal injuries. Sharp edges of pipes and tools can lead to cuts and abrasions. Exposure to hazardous substances, such as solvents and adhesives used in pipe joining, is a concern, as is the potential for contact with biological hazards present in wastewater. Electrical hazards may arise when working near existing wiring or appliances. Additionally, noise from equipment operation can affect hearing, and there is a risk of fire or explosion when working with flammable materials or near ignition sources.
