Read the following scenario and answer questions.
Working for an oil drilling company in the oil sands region of northern Alberta can be very lucrative, even for workers in entry level jobs. Workers have moved to Fort McMurray and other northern Alberta towns in the thousands, from all over Canada and even from overseas. However, the work is demanding and the climate ranges from very hot to extremely cold. Oil drilling crews need to work as quickly and as efficiently as possible as every hour of operation represents a sizeable investment in machinery, labour, and land lease costs. Crews have to move regularly from one site to another site because either the well goes into production or the well comes up dry. Oil drilling companies tend to be very safety conscious because of the hazardous nature of the work; it is not uncommon for workers to experience injuries to extremities (arms, legs, hands, and feet) as well as blows to the head. Fatalities are less common but not unknown.
-Given that engineering interventions are not always possible in this type of work, what would be the next best way of protecting oil rig workers?

A) keeping the drilling rig as clean as possible to avoid trips and falls
B) responding effectively to emergency situations to get medical aid
C) mandatory use of hard hats and safety goggles to avoid contact injuries
D) developing, teaching, and reinforcing safe work habits for every task
