Toxic Fumes To Watch Out For In Your Lab

fume hood cupboard Malaysia is toxic

Fume hood cupboard Malaysia is a vital lab equipment for a good reason. It protects you and the lab itself from toxic fumes as well as its spread. The fumes are captured and released through a ventilation system, away from the work area. Gas masks may also be used to protect your own face from the fumes.

But how do you know which fumes are toxic? What do they look or, heaven forbid, smell like?

Hydrogen sulfide (H2S)

Known for its “rotten egg” like smell, hydrogen sulfide (H2S) is common in manufacturing processes and chemical substances. Commonly associated with raw sewage, animal products, the pulp and paper industry, and oil refineries, hydrogen sulfide is also a byproduct of other products such as pesticides, pharmaceuticals, plastics and even breweries. 

The toxicity of H2S emissions are dangerously high, inhaling them results in irritation, unconsciousness, memory loss, and in severe cases, death. 100 ppm (parts per million) of H2S exposure is highly toxic enough to bring lethal consequences, even at low concentration levels. Workers are recommended to leave the affected area if a concentration of 10 ppm is detected.

Carbon monoxide (CO)

Carbon monoxide (CO) is an odorless, colorless and highly toxic gas that is generally found as a source of energy and reducing agent in industrial processes, as well as a byproduct of incomplete combustion. It is also associated with internal combustion engine exhaust.

Red blood cells will not be able to effectively transport oxygen because CO bonds with the hemoglobin molecules inside them. Prolonged or repeated exposure to the gas results in nausea, restlessness, euphoria, injury, illness and death. Though high concentrations can lead to immediate respiratory arrest or death, the long term effects of chronic exposure in low concentrations can take a greater toll to workers. 

50 ppm is the limited amount of exposure, while maritime workers need extra attention if the CO concentration is higher than 100 ppm. 200 ppm and above is considered highly dangerous.

Nitrogen Oxides

Nitrogen oxides come in seven different gases, the most common are nitric oxide and nitrogen dioxide. Common in several consumer and industrial environments, nitrogen oxide is the reason why air pollution occurs, reducing its quality. Nitric oxide is often emitted from vehicles, agricultural processes or as a fossil fuel byproduct. Nitrogen dioxide is commonly used in the making of rocket fuels and explosives.

Health effects can range from eye, skin and respiratory tract irritations to lethal circumstances. 25 ppm is the allowed limit of exposure of nitric oxide, while 100 ppm is already considered lethal. For nitrogen dioxide, 5 ppm is a limit. 20 ppm is also dangerous.


Commonly seen as widespread smog among cityscapes, ozone is toxic to both humans and plants. It may be natural in the upper atmosphere of the Earth’s stratosphere, but large concentrations on ground level can be emitted by chemical reactions from vehicle exhausts or gasoline vapors. 

Decreased lung function, sunburns, respiratory infection and skin cancer are among the negative human health effects of ozone. 0.10 ppm is the limited level of ozone exposure. Extreme caution is advised when working near ozone for more than eight hours.

Organic solvents are highly toxic and flammable. They are carbon based substances capable of dissolving one or more other substances. Usually found in products such as kerosene, gasoline, paint strippers and degreasers. Higher concentrations and long exposure can affect your central nervous system, as well as making you dizzy, drowsy, hard to concentrate, confused, feeling headaches and sending you to a coma. Death is the last symptom.

As some solvents are commonly used in daily life, it is advised to read warnings about identified toxic gases you may encounter to protect yourself in the long term.

What Exactly is Medical Equipment Supplier in Selangor?

Did you know that medical device manufacturers are constantly looking for distributors?

In summary, a Medical Equipment Supplier in Selangor is a collection of people who ship or supply equipment to hospitals, clinics, or other medical facilities. 

This medical device distributor is in high demand from both agents and consumers. The fundamental reason for this is that the price is determined by the market price. It may even be less than the market’s average selling price.

This is done since the product will be used by other companies. Nonetheless, this distributor will profit from its sales. Because the difference between the prior manufacturer’s buy and the selling price has been made. Taking the equipment from the distributor is considered as more profitable for the hospital or clinic. The reason for this is that this distributor is the second businessperson after the manufacturer. That is, the selling price is lower than the price when purchased at the second branch, and so on.

Benefits of Medical Equipment Supplier in Selangor

Medical device manufacturers and distributors play a critical role in medical device procurement. Where this will have a direct impact on the services provided by health institutions such as hospitals, health centres, clinics, and doctor’s offices. Because this medical institution requires medical equipment renewal and supply from distributors and importers of medical devices in order to assist the implementation of optimal health services.

Medical equipment is required to assist health-care providers’ performance. Treatment and managing efforts in the field of health are impossible without medical equipment.

How to Choose The Best Medical Equipment Supplier in Selangor?

Medical Equipment Supplier in Selangor can be analyzed and assessed based on several things, namely:

Availability of Tools and Medicines

The provision of medical products and devices will be easier if you find the right distributor. This distributor will supply all the products you have always needed. Good products that can last a long time until the product is used up. What needs to be considered is whether this distributor provides a complete product or not. At a minimum, the product you need is already in the company.

Their Service

This service affects the convenience in the buying process. Friendly and fast service will minimize delays in procuring medical equipment or products. Keep in mind that sometimes you need health products in a short period of time. This is due to the large number of patients who need it for the healing process. Hence, the speed of procurement will be better to maintain the reputation of the clinic.

Payment System

This third tip is useful for making purchases easier. The payment system offered should not be a hassle for you. Due to the fact you have a lot of work that demands speed in serving patients. If your time is wasted on the process of paying for medical products, the clinic’s reputation will be negative in the eyes of the patient. Indirectly, this reduces the confidence of people who need treatment.
