Which grоup оf glutаthiоne is more reаctive аs a nucleophile - the thiol or the thiolate anion?
The sаwmill where the аccident оccurred hаs a city water line running undergrоund (thrоugh a vault) along the front of their property. The below-ground vault, which measures twelve feet long, six feet wide, and eight feet deep with a 30-inch utility hatch at the ground level, was installed in 1978 to house a backflow device on the city water line. A backflow device is required to protect the city water supply from possible contamination in the event of negative pressure on the water line. The sawmill's fire protection system connects to this water supply and requires a backflow device. The city mandates the annual inspection of backflow devices by a person trained and certified in cross connection control. The independent contractor (the victim) called the superintendent of maintenance on October 6, 1986, to set up a date and time to inspect the backflow device on the water line. The date and time mutually agreed upon was October 10 at 3: 30 p.m. The contractor arrived at the sawmill at 3:30 p.m. on October 10 and proceeded with the inspection, which he had completed annually for the past three years. The contractor removed the steel hatch and lowered a ladder into the eight-foot-deep vault. There were 14 inches of water in the bottom of the vault. At 4:00 p.m., a truck driver stopped at the sawmill office to inquire about a load of lumber he was to pick up. When he walked out of the office, he noticed the victim's truck and an open utility hatch close to where he would have to drive through. He walked over to the open hatch and saw a body in the water at the bottom of the vault. The driver went back to the office and reported a man was down in the vault. The secretary called the emergency squad. After calling the emergency squad, the secretary and truck driver went outside to the utility hatch. The secretary called for help, and the first to arrive at the scene was the shipping supervisor, who entered the vault in a rescue attempt. A few seconds later, one of the maintenance men arrived on the scene and descended into the vault to assist in the rescue. The men did not have respiratory protection on, and within two or three minutes, both men had passed out. Two policemen arrived at the scene, entered the vault (without respiratory protection), and had to be helped out. The paramedics arrived and attempted rescue (without respiratory protection) and also had to be helped out. The firemen arrived on the scene, donned their breathing apparatus, and went in to remove the three men at the bottom. Two were face down in the water (the contractor and the shipping supervisor), and the third man (the maintenance man) was in a sitting position against the wall, his head was not in the water. Firefighters transported the three victims (the contractor, the shipping supervisor, and the maintenance man), the two police officers, and the two paramedics to a local hospital. The contractor and shipping supervisor were pronounced dead on arrival by the attending physician. Doctors declared the maintenance man as in serious condition. The hospital staff treated and released the two policemen and two paramedics. Test of the atmosphere in the vault by the state investigators revealed the following: 02 7% C02 > 3% % LEL Negative H2S Negative Provide a comprehensive explanation, including specific regulations, for questions 1-4. Your task is to provide as much information/regulations to prevent this accident from happening again. Identify the specific OSHA regulations that should be followed when entering a confined space. Is this a permit-required confined space? Why or Why not? Be Specific Identify the violations of the OSHA regulations that could have prevented this incident. Example: ABC Contracting Co. was replacing a skylight on the roof of a single-story house. After removing the skylight, the employee went to discard the frame in a waste bin, and another employee was walking up to the existing hole in the roof carrying the replacement skylight. He tripped over debris left on the roof and fell. His hammer went through the hole and struck another worker below in the head. He was treated at the hospital and released with a four-inch laceration on his head and a headache. Regulations to prevent this accident from happening again. 1926.501(b)(4)(i) - Each employee on walking/working surfaces shall be protected from falling through holes (including skylights) more than 6 feet (1.8 m) above lower levels, by personal fall arrest systems, covers, or guardrail systems erected around such holes. 1926.501(b)(4)(ii) - Each employee on a walking/working surface shall be protected from tripping in or stepping into or through holes (including skylights) by covers. 1926.501(b)(4)(iii) - Each employee on a walking/working surface shall be protected from objects falling through holes (including skylights) by covers. Identify the Personal Protective Equipment that should have been worn in this scenario. Identify the Physical Hazards: Be Specific Identify the Safety Hazards: Be Specific
