A few days ago, another company has been cited for safety and health violations after being inspected by OSHA that started in August 2009. The company is C&W Industries in Union Springs, Alabama, which provides material handling systems.
According to ohsonline.com, there were some safety and health violations that were found during OSHA inspection. These violations caused the company to be cited for $59,250 of penalties. (more…)
Hydrostatic test is used for confirming mechanical integrity of installed pressure vessels and pipe lines. It has to be completed before putting the pressure vessels and pipe lines in use.
According to ASME Section VIII Division I, hydrostatic pressure is conducted at the pressure of 1.5 times design pressure. If a vessel is design for holding 1.0 kg/cm2.g pressure, the hydrostatic pressure test has to be done at 1.5 kg/cm2.g. (more…)

There are many drain valves around the plant site. These valves can be installed at equipments or pipe lines. Generally, they are operated only at certain conditions such as for draining condensate and depressurized equipment or piping line. In this case, we talk about ball valve with valve handle type as shown by the image on left.
However, these drain valves may be operated accidentally, hit by plant operators or misoperation, which potentially creating an emergency situation. As an example, if the drained material is highly flammable liquid. (more…)
Because carbon monoxide is odorless and colorless, many workers in the plant site do not realize its existence in the workplace. Thus, preventive measures hold fundamental safety function in order to reduce carbon monoxide generation, avoid concentration buildup, alert workers about its existence and prevent carbon monoxide poisoning.
You may have established some preventive measures against CO. But the list below may give you another idea for completing hazard controls against CO. (more…)
Carbon monoxide (CO) or carbon oxide is one of the toxic gases that are commonly found in chemical processing plant. It is used as raw material for other chemicals production or generated as by product from certain chemical processes.
Carbon monoxide is a colorless, poisonous (toxic), odorless and tasteless gas. It is non-irritating gas, which is lighter than air. (more…)
According to American Society of Safety Engineers (ASSE) journal article “Slips, Trips & Falls in Construction & Mining: Causes & Controls”, there are for factors that contribute to slips, trips and falls hazards in the workplace. They are workers, machines/equipments, works environment and management.
In addition, OSHA has released the top 10 safety violations for 2009 that placed scaffolding, fall protection and ladder in the list. They are directly connected to sources of slips, trips and falls hazards. (more…)
UN has established hazard codes for hazardous substances. The codes are classified into 9 classes, where certain classes are divided into some sub-classes.
Hazard coding is given based on hazard characteristic of each substance. It is very important to know these hazard codes in case of hazard controls.
Here are these 9 hazard codes established by UN. (more…)
