Safety Issues stemming from Roof Insulation
The installation of insulation products in the roof void of a domestic dwelling can create safety hazards. These hazards can be separated into two main types: hazards to occupants and hazards to tradespeople and others who enter the roof void.
Hazards To Occupants.
Electric Shock - Installation of insulation that conducts electricity such as metal foil that is interacts with electrical sources within the roof void and is also in contact with metal roof sheeting guttering and down pipes. This can occur as a result of poor installation of the insulation, poor electrical work, rats, possums and poor electrical maintenance.
Fire - Where insulation is poorly installed or is dislodged by following trades and as a consequence covers hot light fittings, the risk of fire is increased. Interaction of conductive insulation with poor electrical work can also be a source of fire.
Hazards to those entering the roof void.
Fall Hazards - It is essential for anyone entering a roof void to be able to check that the roof frame member that they will rely on to support their weight is in good condition and able to do so. Were insulation is installed wholly or partly covering these members a significant hazard exists end the roof void should not be entered.
Electric Shock - Installation of insulation that conducts electricity such as metal foil that is interacts with electrical sources within the roof void.
Toxic Dust - Roof Voids can contain dust and small particles that are a hazard to human health. the include mould spoors, pesticides, asbestos and fibre glass. Anyone entering a roof void should wear appropriate Personal Protection Equipment.
Heat Stroke - The air in roof voids can reach very high temperatures in summer and consciousness can be lost after only a short time. People should not enter roof voids where such conditions exist.
