ball valve
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. Read the rest of this entry »

Carbon monoxide detectors play an important role in preventing carbon monoxide poisoning. It detects carbon monoxide gas at certain level in workplace and soon warns workers to do necessary measures.
Carbon monoxide detectors are either battery operated or electric. Battery operated CO detector needs to be replaced the battery after being achieved its service life.
There are three types of CO detector sensors available in the market. They are electronic sensor detectors, calorimetric sensor detectors and Metal Oxide Semiconductor (MOS) Sensor. Electronic sensor detector is the most sensitive detector, but the cost is higher than other types. Study their advantages and disadvantages before making any purchase. Read the rest of this entry »

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. Read the rest of this entry »

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. Read the rest of this entry »

In December 2009, I noted a chemical plant accident in China, which caused 3 people died. The accident occurred when workers were handling carbon black.
Another accident that grabbed my attention was toxic gas leak (hydrogen sulfide, H2S) that caused 1 engineer died at Thai Rayon Public Co. Limited, Thailand.

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. Read the rest of this entry »

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. Read the rest of this entry »
