Teacher Burned in Lab Mishap
Two dozen fire departments responded yesterday to Rocky Point High School after a science teacher was burned when a chemical reaction in a science lab touched off a small explosion. The teacher, Anthony Nobre, 26, of Medford, suffered burns over his arm, neck and face. He was taken to University Hospital in Stony Brook, where he was listed in satisfactory condition, according to a spokeswoman. The blast erupted as Nobre put crystallized sodium into a container holding a small amount of water. The Brookhaven fire marshal was conducting an investigation and recommended that the building be closed today.
Mercury Shuts Down Detroit School
Detroit’s Miller Middle School will be closed today and possibly Wednesday while health and environmental officials finish cleaning up a small amount of mercury that students spilled in a science class just before school was dismissed Monday. Students apparently were playing with about an ounce of the toxic substance in a sealed vial when it spilled, said a district spokesman Stan Childress. About 30 students and a teacher were present, he said. There is a possibility that students may have tracked through the mercury because some beads of the substance were found in the hallway, Childress said.
Exposure to Hazardous Chemicals Can Result in acute or chronic health effects
Engineering: Removes or Separates Hazard from Person i.e.:
Administrative:Procedures that Limit Contact with Hazard i.e.:
PPE Should Be Considered Only After Administrative and Engineering Controls Have Been Applied.
Minimum Recommended PPE:
Chemical Resistant Gloves, Splash Proof Goggles,
Lab Coat, Face Shield, and Rubber Apron when Necessary
Should be based upon:
Find Out More about Glove Selection by Reviewing Material Safety Data Sheets (MSDS) or from Glove Supply Companies.
Labs are required to supplement course material with site-specific information & training including:
Conduct a yearly inventory of chemicals and update the file of material safety data sheets (MSDS) to prevent the accumulation of orphaned chemicals
Some of these chemicals become unstable, react with the container, slowly degrade or evaporate
Standard requires that
ALL Containers Must be Labeled With:
Chemical Name & Physical/Health Hazards
Name & Address of the Manufacturer & Emergency Contact Numbers
100 Main St., Philadelphia, PA
NFPA Diamonds and HMIS Bars are Color & Number Coded with Hazard Information
DOT Symbols Are Usually Found on Shipping Cartons
Equipment & VentilationWhat Should the Ideal Laboratory Look Like?
Fume Hoods Used For Operations that Give Off:
Flammable or Poisonous Vapors
HOW DOES YOUR VENTILATION MEASURE UP?
Must Be Available in All Lab Areas That Use or Store Chemicals Which Are Corrosive or an Irritant to the Eyes or Skin
Combination Eye Wash & Drench Hose Units at the Sink are Now Available
Fire Extinguishers Must Be:
Two or more well- marked & unobstructed evacuation exits are recommended in a lab.
Consideration should be given to installing ground-fault circuit interrupters on electrical circuits within 6 feet of water sources.It’s Shocking!
