Personal Protective Equipment (PPE)

Personal protective equipment (PPE) is used to protect the user against health and safety risks in the workplace. There are various types of PPE, and they include high-visibility clothing, safety helmets, face masks, respiratory protective equipment (RPE), gloves, protective suit, eye protection, ear protection, and safety footwear (OSHA, HSE). The following is a discussion about five types of PPE and their limitations.

Gloves are worn to protect the hand from extreme heat or cold. It is also worn to protect the hand from rough or sharp objects or surfaces. Gloves also protect the hand from being contaminated with harmful ...

Question 1

PCBs
Polychlorinated Biphenyls (PCBs) are chlorinated hydrocarbons with two phenyl rings. They are stable, resistant to fire and possess good insulating properties. Hence, they were used widely before their ban in 1979, in transformers, capacitors, hydraulic machine lubricants, and oil based paints, adhesives, sealants, insulating and caulking material as well as in light ballasts. (US Environmental Protection Agency [USEPA], 2013). EH&S as well as FS personnel would have to handle PCBs when they indulge in building demolition, renovation, decontamination activities or in case of emergencies such as fire and explosion. PCBs present in electrical and building materials pose a ...

Problem Statement:

When we review the management of Carter’s Cleaning Company, it becomes evident that the business may face several challenges, ranging from hazardous chemicals and risks of explosions due to a lack of training, increased dissatisfaction among Carter Cleaning Company employees, management and communication issues, involving Machineries being motorized by high pressure steam, chemical vapors formed during the process and utilization of caustic chemicals for the purpose of cleaning etc.

Key Elements:

Carter’s Cleaning Company makes use of highly motorized pressure steams thus resulting in Risks of boil over if high steam is injected.

The boiling chemical solvent may perhaps explode.

Chemically precarious waste is frequently being produced.
...

Aim: The aim is to determine the effect of temperature on the rate in which pepsin digests albumen.

Research Question: What is the effect of temperature on the rate in which the enzyme pepsin digests protein (albumen)?
Background Information:
Enzymes are globular proteins acting as catalysts of chemical reactions. An enzyme has an active site: region on the surface of an enzyme catalyzing a chemical reaction involving the substrates and to which substrates bind.
The active site of an enzyme has a unique shape; therefore, the enzymes can only catalyze certain reactions since solely substrates of the same size can fit. The enzyme is therefore specific to its substrate; consequently, the enzyme is seen as ...
