biohazard

Biohazard

Consult the Biological Safety Manual for information on when and where this warning label shall be used for identifying the contents of containers. In general, a "biohazard" is a material that is or has been contaminated with biological entities (capable of reproduction), which are known or suspected to cause disease in humans. For further assistance, contact the Biological Safety Officer at (765) 494-1496.

 

 

 

C


caution

Carcinogens, Reproductive Toxins, or Extremely Toxic Chemicals

This label will be used to designate areas for use of the following select carcinogens, reproductive hazards, and/or substances having a high degree of acute toxicity. Refer to "Chemicals Requiring Designated Areas" web page for a further explanation of the use of this sticker. For further assistance contact the REM Chemical Hygiene Officer at (765) 494-6371.

NOTE: Not withstanding any other prohibitions, placing this sticker at an entrance prohibits the eating, drinking, storage, and/or preparation of food or beverages anywhere inside the room.

don not use

Do Not Use Until Repaired

Once a work order is placed to Zone Maintenance by either your building deputy or REM’s Industrial Hygiene section, a sign will be posted on the fume hood stating the hood is not safe to use and repairs are in process. Failure to relocate or end experiments while repairs are in process poses a health and safety risk to the lab as well as maintenance workers. During the repair process, fume hoods do not provide adequate ventilation for open chemicals.

perchloric acid fume hood warning

Perchloric Acid Fume Hood Label

Special hoods equipped with a stainless steel or PVC duct and properly timed water wash down system. The wash down system must be used following each use of the acid hood. Using perchloric acid in a general lab fume hood may cause the acid vapors to settle onto the ductwork and create explosive perchlorate crystals. Serious injury or fatality may result to hood users or maintenance staff if the acid crystals are exposed to vibration and detonate.

safe for disposal: triple rinsed notice
secondary container label
strong magnetic field

Safe for Disposal: Triple Rinsed Notice 

This label is recommended to identify those containers ready for the regular trash. This label also informs those individuals handling your trash that NO hazardous chemicals are left in the container. For further assistance contact Hazardous Materials Section at (765) 494-0121.

 

 Secondary Container Label

These labels are recommended for secondary containers. If a product is being transferred into a secondary container, you must prepare nd apply this label in accordance to the chemical’s information (product name,
signal word, hazard statement and pictogram). This information can be found on the original container or from the Safety Data Sheet (SDS). If a product is being diluted as part of a mixture, the information will likely need to be changed. Please contact an Environmental Technician at (765) 494-3152 for assistance.

 

Strong Magnetic Field

Do not enter a room with magnetic resonance equipment if you wear a pacemaker without previously consulting a physician. No magnetic of ferrous objects or watches within the 10gauss field. No compressed gas cylinders within the 5 gauss field.
