Laboratory Safety

This policy is intended to outline the general safety guideline and rules for activities which are performed at the CSP Laboratory. 1a

 PPE: Safety glasses, appropriate clothing and gloves must be worn in laboratory at all the times.  Long hair must be retrained so it cannot fall into chemicals.  No eating or drinking in lab or storage of food. 1b

 Always wash your hands if you spilled anything on them and before leaving the lab.  Pipetting should always be carried out by ejectors or bulb and never the mouth.  Use fume hood to perform all the chemical reactions that produces fumes.  Always leave the fume hood running.

 Discard titration samples in designated disposal site. ◦ In our plant the lab sink drains into vacuumed sealed containment area T ◦ Do not mix or drain acid and sodium hypochlorite together or close proximity of time, reaction can release toxic Chlorine gas (lethal dose 100ppm).  Do not carry out unauthorized experiments.  Prior to working with any chemicals, always read and understand the Safety Data Sheets and respective SOPs.  If at anytime you get nauseous, get outside for fresh air, report to authorities.i.e. Shift leads or Plant manager.

 Keep eye wash stations, emergency showers, fire extinguisher and alarm pull- boxes free from obstructions.  Keep emergency exits and all corridors free from obstruction.  Never allow laboratory facility to come in contact with any food or drinking water.

 House Keeping: ◦ Clean benches and counters after the completion of each test. ◦ Broken glassware must be disposed into designated waste containers i.e. glass disposal bin under the counter. ◦ Chemical spill must be contained with spill kit immediately and placed in designated containers. ◦ Labels on incoming containers cannot be removed or defaced. ◦ Used empty chemical bottles advised crossed off the label before discarding them in the trash.  (note: Please read SDSs and label carefully before rinsing it with water, keeping in mind possible reactivity when rinsing the bottles)

Getting Sample :  Must wear designated Lab face shield with visor.  Buttoned full sleeved shirt.  Surgical rubber gloves provided by company, or thicker gloves if needed to protect from heat of hot samples.  Plant required PPE.i.e. Hard hat, respirator, steel toe boots and safety glasses with side shield must be worn.  Mandatory: carrying a radio on at all times.

 All chemical splashes on the floor or benches or counters must be cleaned immediately.  Pour concentrated acids and alkalis into water and never the reverse.  Dilute the acid and alkalis concentration with large amount of water before discarding into the sink.

 Avoid breathing fumes of these liquids.  Do not handle flammables near hot plate or other source of ignition.  Never discard flammable into the lab sink.  Do not introduce chemicals that are not used or produced by the plant into the process or the lab sink.

 Avoid storing any chemical above eye level.  Don’t store incompatible chemicals together.  Don’t store chemicals near sources of heat or sunlight.  Don’t store chemicals in the hoods or acids on metal shelves  Avoid storing anything on the floor, especially glass bottles. 11

OSHA’s Hazard Communication Standard requires that ALL Containers Must be Labeled With : 12 Chemical Name & Physical/Health Hazards Name & Address of the Manufacturer & Emergency Contact Numbers 100 Main St., Philadelphia, PA

Safety Data Sheets (SDSs) An SDSs must be on file & available for each chemicals in the lab. In our plant we have physical copy in control room and electronic copy in drop box under safety folder.  An SDSs lists: 1, Identification 2, Hazard(s) identification 3, Composition/information on ingredients 4, First-aid measures 5, Fire-fighting measures 6, Accidental release measures 7, Handling and storage 8, Exposure controls/personal protection 9, Physical and chemical properties 10, Stability and reactivity 11, Toxicological information 12, Ecological information 13, Disposal considerations 14, Transport information 15, Regulatory information 16, Other information

14 NFPA Diamonds and HMIS Bars are Color & Number Coded with Hazard Information DOT Symbols Are Usually Found on Shipping Cartons

Yearly inventory of chemicals must be conducted and update the file of material safety data sheets (SDSs) to prevent the accumulation of orphaned chemicals. Some of these chemicals become unstable, react with the container, slowly degrade or evaporate.

 Lab inventory log/orders are done by designated employees every other week, however it does not preclude everyone’s responsibility to keep track of our inventory and reporting to designated personnel if needed. Recordkeeping:  Records retained for duration 3 years plus current.  Includes tests results and written opinions.

 Pass down at the end or beginning of the shift must include: ◦ General lab and plant status. ◦ Any broken lab equipment. ◦ Deviation from normal process operation that effects directly or indirectly to standard lab operations.
