DGS-1 and DGS-2 - MC-20 Repeated failure to follow approved and revised safe work procedures and lack of responsibility by all responsible personnel to safeguard and protect workers from all hazards.  Deep excavation / confined space permits were issued in the office by the Site Engineer and dispatched to the site, the work environment was not inspected by any competent personnel and HSE member prior to commencement of works, the Site Foreman and other workers were not briefed or provided any TBTs of JHA.  Gas monitoring was not being performed as per standard requirements and Contractor's procedures.  The Engineer's Representative visited the site and conducted atmospheric testing with another instrument and recorded H2S levels of 20ppm and CO 5ppm.  At this time there was approx. seven workers in the deep excavation.  Two tests were conducted and the second test recorded a value of 16ppm H2S.  The Contractor's gas monitor as this site was later recovered and taken to the HSE site office were a bump test was performed.  This gas monitor failed the bump test.  This is a serious non compliance and failure in the Contractor's safe work systems that may lead to a severe incident.
