Basic Concept Laboratory Tech M
Basic concept in Laboratory Techniques M. Sc. 2nd Semester Subject: Basic Concepts in Laboratory Techniques 1 Code: PGS – 504 (0 + 1) Chemical Use Guideline 1) Never use a product that doesn't have a label to reference. 2) Don't mix chemicals without specific authorization from the formulator. 3) Always use personal protective equipments. 4) When pouring chemicals, pour concentrates into the water and not vice-versa. 5) Never pour chemicals into an empty, unlabeled container. 6) Don't store flammable chemicals near a source of heat. 7) Pesticides, fungicides, etc. always must be stored in a safe and elevated position. Basically, there are four types of chemicals • Toxic chemicals : These are chemicals that are poisonous to you, and can act upon the body very rapidly. Hydrogen sulfide and cyanide are examples of toxic agents. • Corrosives : This type of chemical is usually an irritant. Corrosives can damage your body by burning, scalding or inflaming body tissues. Examples are chlorine and HCl acid. • Flammables : Flammables are the chemicals that burn readily. They may explode or burn if sparks, flames or other ignition sources are present. Examples are gasoline, benzene and ethyl ether. • Reactive : Reactive chemicals are those that require stability and careful handling. Some of them can explode or react violently if the container is dropped or hit. Nitroglycerine is an example. Basic Tips of Safe Chemical Handling 1. Read the label 2. Dress the part 3. Follow directions 4. Know emergency procedures 5. Be careful! 6. Report any suspected problems 7. Keep your work area neat, clean and organized 8.
