A Control Limit refers to the maximum permissible concentration of asbestos in the atmosphere, as defined by the Control of Asbestos Regulations (CAR). This limit is set at 0.1 fibres per cubic centimetre of air, averaged over a continuous period of 4 hours.
Asbestos, a naturally occurring mineral, was widely used in construction and other industries due to its heat resistance and durability. However, when disturbed, asbestos can release tiny fibres into the air. If inhaled, these fibres can cause serious health problems, including lung diseases and cancer.
The Control Limit is a crucial part of health and safety regulations related to asbestos. It is determined using a specific method recommended by the World Health Organization (WHO) in 1997, or an equivalent method approved by the Health and Safety Executive (HSE). This measurement helps to ensure that workers and others in the vicinity are not exposed to harmful levels of asbestos.
It’s important to note that the Control Limit is not a ‘safe’ level of exposure, and all efforts should be made to reduce asbestos levels as much as possible. If asbestos is present or suspected in a building or other structure, it’s essential to seek professional help to manage the risk.
Understanding and adhering to the Control Limit is a key aspect of managing asbestos risks and ensuring a safe environment.
