The absence of Construction (design and management) regulations 2007; part IV or similar enactment to address the welfare of employees and impose certain obligations on the contractor resulted in the loss of many lives which otherwise could have been saved. The dam claimed the lives of an estimated 112 people. However, only 96 of them are reported to have died. The toll does not include those whose death was caused as a result of heat, heart stroke, etc. ( www.wikipedia.org ). The construction (Design and Management) regulations 2007; part IV imposes obligations on the part of the constructor pertaining to the health and safety of employees in construction sites. In the Hoover dam case, safety measures were not taken to ensure the safety of the people working at the site. Sec.25 (10) of the act provides that, “every contractor carrying out construction work shall comply with the requirements of regulations 26-44 in so far as they affect him or any person carrying out construction work under his control or relate to matters within his control”. Sec.30 (1) of the Construction (Design and Management) regulations 2007 further provides that “so far as is reasonably practicable, explosives shall be stored, transported and used safely and securely” ( office of public sector, UK ) subclause (2) of the same section further goes to say “without prejudice to Para (1), an explosive charge shall be used or fired only if suitable and sufficient steps have been taken to ensure that no person is exposed to risk of injury from the explosion or from projected or flying material caused thereby” ( ibid ). This section protects the workers from any danger they might be exposed to while undergoing construction work. Most workers in the Hoover dam died as a result of carbon monoxide. This sub-section imposes responsibility on the constructor or his agent to ensure that no such explosives or emissions are at the site while construction takes place. Further sec.35 provides that the contractor must take every case possible to prevent any act of drowning from taking place during the course of construction. The section further stipulates that the contractor must as far as is practicable minimize such risk. This was not adhered to in Hoover dam construction. It is known that the first person to die in Hoover dam construction J.G. Tierney, a surveyor died as a result of drowning. Proper care was not availed in order to ensure his safety even after when the contractor was aware of the danger at the site. The civil attempt by workers to sue the company using civil law may not yield the proper outcome i.e. justice. Civil law is wide enough to cover specific provisions which could impose liability on the part of the contractor. However, this was the only law available at that time to rely on. The legal principle under civil relied on here was a strict liability. This rule has been best illustrated in the case of Rylands v. Fletcher (1886) LR 3HL 330 , where Blackburn J. held that “the rule of law is that the person who for is on purpose, brings on his land and collects and keeps there anything likely to do mischief if it escapes, must keep it in his peril, and if he does not do so
