Self-contained self-rescuers (SCSR) are an essential piece of equipment for mining staff. These easily portable devices provide a miner with breathable air, should the surrounding atmosphere lack oxygen or become contaminated.
Despite all safety precautions, accidents can and do happen, and a fire or explosion in a mine could leave workers without rescue for some time. Should a miner need to await help following a crisis or make their own way to safety, they must be able to do so with access to uncontaminated, breathable air. An SCSR can provide a vital lifeline in an emergency, and is an integral piece of the miner’s equipment arsenal.
Self-contained self-rescuers: our range
Among our range of SCSRs is the Mine Safety Appliances (MSA) W65 Self-Rescuer Respirator, an air-purifying oxygen mask designed to protect against carbon monoxide and other toxic gases emitting from underground mine fires or explosions. Immediately ready-for-use, the latex-free mouthpiece and nose clip allow for a smooth flow of safely breathable air to the user. Designed to be strapped to the head permitting hands-free operation, the device can be carried on the belt or over the shoulder when not in use. The hermetically sealed, stainless steel container of the W65 boasts a long life expectancy of up to 15 years, with an in-service life of 10 years, and can provide a wearer with clean air for up to four hours.
We also offer products from Ocenco, such as the EBA 6.5. This closed-circuit apparatus uses compressed oxygen, rather than the chemical-based breathing solutions available from alternate vendors. This allows for extended life of the product as these units can be repaired and refurbished after use where others cannot, giving the wearer with the security of a 15-year useful life. A clear case allows the miner to quickly and accurately assess the condition of the device, which can be manually adjusted to provide the user with up to eight hours of respiratory protection.
Another Ocenco SCSR available is the M-20, a belt-borne device which is particularly useful in tunnels and other confined spaces. At just over six inches square and three inches thick, this is the world’s smallest SCSR, using compressed oxygen to provide respiratory protection for up to 32 minutes. The user can quickly check the oxygen supply through the clear case, and much like the EBA 6.5, this is a device which can be upgraded and maintained for up to 15 years.
