||Results of tests to determine the minimum energy level required to explode a methane-air mixture or to fire an electric detonator, and the maximum electric charge that can build up on the body of a miner with normal clothing and equipment. Taking into account a safety factor of 2.5, this charge can be maintained within the limits of safety by adopting maximum dielectric strengths of 5 x 108Ohm for footwear and 1 x 109Ohm for clothing fabrics. Fabrics made of cotton, linen and fibres containing less than 50% synthetics meet these requirements.
