Truss Construction Shop is deciding to evaluate the safety and health of their shop is by using a Program Evaluation Profile, or PEP. This form, provided by OSHA, is used to “assess employer safety and health programs in general industry workplaces” (Program, 1996). Regardless of if the accident mishap is due to personnel issues, it is exceedingly important for companies to ensure workers are operating in a safe and protective environment. OHSA’s PEP evaluates a work center full circle. It contains six elements, to include management leadership and employee participation, workplace analysis, accident and record analysis, hazard prevention and control, emergency response, and safety and health training (Program, 1996).

This conclusion can be drawn because of celery’s large drop in pH and the data’s resemblance to the water data meaning celery cannot hydrolyze ions and keep a constant pH. Liver’s pH only changed by .47 which is not a dramatic change and can fall within scientific error and strongly relates to the alka seltzer data. Which, leads to the conclusion that liver does contain a buffer and is able to keep the same amount of hydrogen when acid is added. In conclusion, celery does not contain a buffer to keep pH constant and liver does have a buffer and can hydrolyze

To avert future incidents, the firefighting crew and workers within hazardous material facilities should enroll for the hazardous material (HAZMAT) awareness course. This would be vital to perfecting their recognition, awareness, and response to varied types of explosions as well as the ability to employ the appropriate notification protocols in the event of an explosion. 4.2 Preventive

The third test we conducted were eutrophication tests, phosphate and nitrate tests, and acidity and alkalinity tests. The first one was a ph meter test to see if the water in the creek was acidic, neutral, or alkaline. On the ph meter we got a 7 which is neutral, and that’s good. For the alkalinity test we got a 13 which is good, and for the acid test we collected rocks and got 65 total. Of the 65 rocks only 29 did NOT neutralize acid which is really good so the creek should not be acidic.

HEALTH AND SAFETY The importance of health and safety in the mining is to make sure that the workers are safe. Secondly protected and productive extraction and transforming is one of the objectives of mining companies. The hazards related with the mining operating are more since they need to work on remote and less sociable locales. Thirdly it is the company’s duty to have a legitimate security system in place which guarantees the protected workplace in the mines. Mining organisations keep on focusing on the need of consideration on making a safe working condition for all their employees.

It includes several modules that are equally important to be understood by transportation workers. General awareness - This section teaches employees to recognize hazardous materials in the workplace. Safety training - This training teaches about emergency response techniques in the event of an emergency at the workplace. It also teaches proper handling procedures and risk avoidance. Function-specific training - This portion of the training is more specific to the the exact job that you will be doing.

(“7 million,” 2014, para. 7). Air pollution is mainly common in developing countries from the extensive amount of industrialization and urbanization that is taking place. Poorer countries and communities cannot afford the ability to protect themselves, which is why there is so much suffering in these communities. In China alone, life expectancies are about 5.5 years lower than the United States because of the cardiovascular and respiratory mortality (Chen, Eventstin, Greenstone, & Li, 2013, para.

To have gotten a 0% error between the experimental and actual value for CH3COOH, the pH would have been measured at about 4.75, which is slightly more acidic than 4.80. The percent error was calculated to determine how accurate the Ka of acetic acid was: Since the calculations yielded a 20% error, this shows that experimental error occurred during the experiment. Factors that could have affected the results included improper reading of the meniscus for volume of NaOH, not allowing the NaOH to fully drip into the buret after removing the funnel, adding too much acetic acid after the indicator flashed pink to get an inaccurate equivalence point, and not allowing the solution in the beaker to mix thoroughly to get an accurate reading from the pH

Heather Whipps supports this idea in her article, How the Black Death Changed the World, by stating, “The Black Death-as it is commonly called-especially ravaged Europe, which was halfway through a century already marked by war, famine and scandal in the church…” (Whipps 1-2). The war had already weakened Europe financially, causing them to have a lack of resources. Due to these factors, people started moving from the countryside to city-side to better get those resources. Since cities were so condensed, it was easier for germs to spread, especially an airborne disease like the plague. Whipps continues, “Densely populated Europe, which had seen a recent growth in the population of its cities, was a tinderbox for the disease” (2).

Government settle some hazardous facilities, such as incinerators, landfill, and some wastes sites in the areas where poor and minority located. “One of the landmark events in the development of the environmental justice movement in the U.S. was the 1982 battle over the siting of a hazardous waste landfill in Warren County, North Carolina.12 Warren County was one of the poorest counties in the state, and had the highest percentage of black residents; Afton, the community chosen for the landfill, was over 84 percent black. Despite low incomes, an exceptionally large percentage of residents in this area owned their own homes” (Massey, 5). According to this report, there was tens thousands of cubic yards of soil that was contaminated by PCBs. More importantly, the landfill was located above the water table only five to ten feet.
