Regulation 4.11 – Precautions around misfires, sockets and old explosives
According to Regulation 4.11, you, the employer, 'must take reasonable measures to ensure that a written procedure is prepared and implemented… to prevent persons from being exposed to significant risks associated with misfires, sockets and old explosives.'
Now, when it comes to misfires, your procedure must include measures which ensure:
That no person gains access to any misfired holes which is not 'immediately' dealt with – this involves CLEARLY marking the misfired hole, barricading it off and reporting it to every shift that comes afterwards until the misfired hole has been dealt with completely.
. That explosives are ONLY taken out of any misfired hole after consultation with the relevant explosives manufacturer or supplier.
That the person who extracts explosives from a misfired hole makes sure that, as far as is reasonably practicable, ALL explosives are removed and recovers all of them.
These are three precautions you should take to ensure safety with regard to misfired holes, sockets and old explosives.
