Chemical & Response Details
| Also known as | PCBsChlorinated biphenylsAroclorAskarelChlorinated diphenyl |
| Appearance | Colorless to light yellow oily liquid with a mild aromatic or odorless characteristic. Viscous consistency, denser than water. |
| Flash Point | Typically 170-290C (338-554F) depending on chlorine content |
| Boiling Point | 340-375C (644-707F) depending on isomer mixture |
| Vapor Density | Heavier than air (relative density >5) |
| Water Reactivity | No significant reaction with water; insoluble and will sink or form separate layer |
| Extinguishing | Alcohol-resistant foam, dry chemical, CO2; water spray for cooling only |
| PPE | ⚠️ Level B minimum with SCBA; full chemical-resistant suit; avoid skin contact due to bioaccumulation risk |
| Isolation | ERG 171: isolate spill/leak area 25m in all directions; if tank/rail car involved in fire, isolate 800m in all directions |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Some may burn but none ignite readily.
- Containers may explode when heated.
- Some may be transported hot.
- For UN3508, Capacitor, asymmetric, be aware of possible short circuiting as this product is transported
- Polymeric beads, expandable (UN2211) may evolve flammable vapours.
- Inhalation of material may be harmful.
- Contact may cause burns to skin and eyes.
- Inhalation of Asbestos dust may have a damaging effect on the lungs.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
