Oil and gas workers have some of the most dangerous jobs in the country. In fact, according to the Bureau of Labor Statistics, about 4.2 percent of all oil and gas workers are hurt on the job each year. A great many of these incidents involve an oil rig accident, suffered off-shore on the decks or in the wells of a drilling operation. To help workers become more aware of the dangers and hazards associated with their job, company usually put helpful guide, noting common types and causes of oil field accidents, so these can be avoided and prevented. There are a number of types and kinds of oil rig injuries that can be suffered on the job. Some are due to negligence or error on the part of employers or co-workers, while others are simply a hazard of the oil and gas industry. Common types of oil field accident includes: burns, brain and head injuries, exposure to toxic fumes, amputations. Some of the common causes of oil field accidents are Gas leaks, High pressure in wells, Falling of objects, etc.Based on what you study in the course and understanding on above case study a. What are direct causes of accident and explain in details with an example related to acts and condition(2.5 marks each)

The Oil and Gas (O&G) industry is by its nature a high risk industry. The industries’ products, hydrocarbons produced and transported, supply the world market with substantial amounts of fuel and raw product for a number of industrial activities. Therefore the O&G industry handles large quantities of flammable and hazardous substances in the high energy environment encountered subsurface with high pressure and temperature scenarios, explosion prone environment, electrical hazard, falling hazards, and mechanical structure failure. In some cases the risk situation is complicated by a highly toxic gaseous by- product - hydrogen sulfide (H2S). These high energy situations and severe forces call for highly developed Health, Safety and Environment (HSE) Management Systems and Cultures. Despite the high-performance risk control approach the O&G industry has implemented, the industry has seen a number of major accidents with extensive consequences. A major accident involving hydrocarbons puts at stake the lives of personnel working at the site, the life and health of populations in neighbouring communities. Based on your understanding and what you study in the course answer the following questions: a. How chemical hazard is considered as major risk to oil and gas industry and what are the causes of it? (risks – 2.5 marks, causes – 2.5 marks)

Explain how you would decide what light levels are required on a work surface for particular workplaces. Give at least five examples of different visual tasks and state the range of illuminance that is acceptable for that task.

.) An MSDS gives information about

1. Hazardous chemicals
2. Injuries in the work place
3. Medical examinations
4. Machinery maintenance
5. None of the above

9.) OSHA’s mission is to

1. Protect the safety and health of the general public
2. Protect the safety and health of the U.S. workforce
3. Ensure that all workers are subject to annual physicals
4. Develop medical and exposure records for all workers
5. None of the above

10.) The right of workers to seek safety and health in the job without fear of punishment is spelled out in:

1. State OSHA Laws
2. OSHA Technical Standards
3. Section 11(c) of the OSHA Act
4. Section 5(a)(1) of the OSHA Act
5. OSHA 300 Requirements

11.) To protect against pipe leakage of a gas into a confined space after a shutoff valve has been closed, the practice of the absolute closure of the pipe by the fastening of a solid plate between two flanges that completely covers the pipe’s bore and with no leakage beyond the plate is referred to as ______________.

1. Double blocking
2. Double bleed
3. Blanking/blinding
4. Inerting
5. Line breaking
