What does the corrosion symbol mean?

The corrosive symbol is used to warn against chemicals that may damage living tissue on contact. The image shows a chemical spill causing the corrosion of a hand a surface material.

What does it mean if a product is corrosive?

Corrosives are materials that can attack and chemically destroy exposed body tissues. Corrosives can also damage or even destroy metal. Corrosive materials are present in almost every workplace. Acids, bases (which include caustics or alkalis), and other chemicals may be corrosive.

What are the precautions needed for the safe storage of acids?

Acids – Concentrated acids must be safely stored inside a suitable cabinet as detailed above. Small quantities of dilute acids, such as used with pH meters, may be stored on the bench providing they are appropriately labelled. Fuming acids, acids chlorides should be stored in ventilated enclosures.

What to do if corrosive is spilled on skin?

If you spill an acid or base on your skin, immediately wash well with water. Strong bases react with the oils in your skin to produce a soapy feeling layer. Rinse until well after that feeling is gone. Do not attempt to neutralize a spill on your skin.

What is the hazard symbol for corrosive?

Exclamation Mark: An immediate skin, eye or respiratory tract irritant, or narcotic. Gas Cylinder: Gases stored under pressure, such as ammonia or liquid nitrogen. Corrosion: Materials causing skin corrosion/burns or eye damage on contact, or that are corrosive to metals.

What precautions should you take when working with strong acids and bases?

Personal protective equipment:

• Face protection, such as a face shield, is required when working with large volumes of liquid acids and bases.
• An apron or disposable gown must be worn when working with large volumes of liquid acids and bases.
• Acid-resistant gloves must be worn when handling acids and bases.

How do you handle corrosive materials?

Special Handling

1. Never store corrosive liquids above eye level.
2. Always add acids or bases to water (and not the reverse).
3. Segregate acids and bases in storage.
4. When mixing corrosive solids with water, always slowly add the corrosive solid to the water, stirring continuously.

What are the safety precautions when working with corrosive substances?

When working with corrosive substances you should use precaution – non-corrosive gloves, eye protection and lab coats are all musts. These are highly harmful substances and, in extreme cases, can even cause death if you swallow, inhale or absorb them through your skin.

What type of safety glasses should I wear when handling corrosive chemicals?

Review the material safety data sheet (MSDS) prior to using this material. Safety glasses that meet the ANSI Z.87.1 1989 standard should be worn whenever handling corrosive chemicals. Ordinary prescription glasses WILL NOT provide adequate protection unless they also meet this standard.

How do I identify corrosive chemicals?

Corrosive chemicals will be identified with the pictogram shown below. In addition, Section 2 of the Safety Data Sheet (SDS) will include one or more of the hazard statements indicated below. H290 May be corrosive to metals • H314 Causes severe skin burns and eye damage. H318 Causes serious eye damage

What gloves should be worn when handling corrosive chemicals?

Gloves should be worn when handling corrosive chemicals. Nitrile gloves should be adequate for handling most of these in general laboratory settings. An MSDS should be reviewed if handling may involve extended or high exposure to lab personnel to ensure adequate skin protection is provided.
