Like many trades, plumbing can be a dangerous job. It is important to take all reasonably practicable measures to keep customers and yourself incident and injury free.

Biohazard waste
Plumbers regularly come into contact with biohazard waste. It's the nature of the job, but that doesn't mean you should be complacent about it. According to Safe Work Australia, communicable diseases from work-related exposures to biological hazards such as sewage have been estimated to cause 320,000 deaths across the globe each year. In addition to this, plumbers are regularly exposed to other biohazards such as mould, bacteria and algae. Don't risk it – make sure appropriate protective clothing and equipment is used.

Confined spaces
Plumbers may spend much of their time working in confined spaces, where they are at risk from contaminants, including airborne gases, vapours and dusts, that may cause injury from fire or explosion. They may also be exposed to high concentrations of airborne contaminants that may be harmful to health. For example, one plumber was fined $220,000 after an employee suffered from carbon-monoxide poisoning. Another potential hazard for plumbers in confined spaces is that of drowning, if water sources are not adequately cut off.

The Safe Work Australia confined spaces code of practice outlines the necessary steps and precautions for avoiding illness and injury.

Electricity
The Master Plumbers' Association calls electricity ‘plumbing's hidden killer'. Metal pipes are often conductive and so gloves which provide insulation should form part of a plumber's tool kit, as should a plumbing voltage monitor and a volt tester. Gloves should be checked prior to every use and replaced every 12 to 14 months. Electrical equipment like bridging conductors should be regularly checked, with appropriate tags on the equipment to verify its safety. The project should be stopped immediately if there is any sign of electricity, so that the power can be disconnected by a qualified electrician prior to continuing work.
