Is dichloromethane a hazardous substance?
Is dichloromethane a hazardous substance?
Classified as a neurotoxin, dichloromethane has been proven to cause damage to the brain and central nervous system (CNS). The Environmental Protection Agency (EPA) has classified it as a probable human carcinogen since high levels of exposure to the chemical has been proven to cause liver and lung cancer in animals.
What is the main hazard associated with dichloromethane?
Brief exposure to Dichloromethane can cause eye and skin irritation and prolonged skin exposure can cause severe chemical burns. Dichloromethane can cross the blood-brain barrier and can result in central nervous system depression with symptoms like drowsiness or dizziness.
What PPE is needed to work with dichloromethane?
What Personal Protective Equipment (PPE) is needed when working with methylene chloride? Eye/Face Protection: Wear chemical safety goggles. A face shield (with safety goggles) may also be necessary. Skin Protection: Wear chemical protective clothing e.g. gloves, aprons, boots.
Is dichloromethane an environmental hazard?
Summary of environmental hazard characteristics Dichloromethane (DCM) belongs to a category of ozone depleting chemicals known as ‘very short-lived substances’ (VSLSs). DCM contributes to depletion of ozone in the stratosphere.
Does DCM penetrate nitrile gloves?
WARNING: Methylene chloride/dichloromethane readily penetrates standard nitrile laboratory gloves (and many other types of gloves).
Can DCM go through gloves?
Gloves made of polyethylene vinyl alcohol and ethylene vinyl alcohol (PVA/EVA) are resistant to methylene chloride. However, many other types of gloves are not recommended for use with methylene chloride including latex, nitrile, neoprene, polyethylene, and butyl rubber.
Why is dichloromethane a bad solvent?
Organic solvents like DCM are dangerous because of their high volatility. This means that they can easily evaporate. Therefore, inhalation is the most common form of exposure to solvents. The toxicity of DCM not only comes from its high volatility, but also from its great stability.
How carcinogenic is dichloromethane?
Dichloromethane was classified as likely to be carcinogenic in humans based primarily on evidence of carcinogenicity at two sites (liver and lung) in male and female B6C3F1 mice (inhalation exposure) and at one site (liver) in male B6C3F1 mice (drinking-water exposure).
What type of chemical is dichloromethane?
organochlorine compound
Dichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine compound with the formula CH 2Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odour is widely used as a solvent. Although it is not miscible with water, it is polar, and miscible with many organic solvents.
Can dichloromethane go through gloves?
WARNING: Methylene chloride/dichloromethane readily penetrates standard nitrile laboratory gloves (and many other types of gloves). Wear two pairs of standard nitrile gloves and work so that gloves do not contact the chemical. Remove outer gloves immediately if splashed.
What type of gloves were used when handling dichloromethane DCM )?
Additionally, skin contact with methylene chloride should be minimized by using methylene chloride- resistant gloves to reduce exposure. Gloves made of polyethylene vinyl alcohol and ethylene vinyl alcohol (PVA/EVA) are resistant to methylene chloride.
Do nitrile gloves protect against dichloromethane?
How do you dispose of dichloromethane in a lab?
Glassware having contained dichloromethane has to be rinsed with acetone before being moved out of the fume hood space to limit inhalation. Methylene chloride has to be disposed of in the appropriate organic waste container, kept closed at all times.

How many sections are there in a GHS safety data sheet?
GHS has harmonized the format and content of Safety Data Sheets (SDSs). There are 16 sections in standard GHS safety data sheets (as shown below). GHS has also set the minimum info required for each section. Section 16 Other information.
What is safety data sheet (SDS)?
Safety Data Sheet (SDS) is a very important document to inform its audience of the hazards of a chemical substance or mixture and provide advice on safety precautions. Some countries may still call this document Material Safety Data Sheet (MSDS).
