| NOTES: |
| a When stored as a liquid monomer. |
| b Although these chemicals form peroxides, no explosions involving these |
| monomers have been reported. |
| c When stored in liquid form, these chemicals form explosive levels of peroxides |
| without concentration. They may also be stored as a gas in gas cylinders. |
| When stored as a gas, these chemicals may autopolymerize as a result of |
| peroxide accumulation. |
| d These chemicals easily form peroxides and should probably be considered |
| under Part B. |
| e OSHA - regulated carcinogen. |
| f Extremely reactive and unstable compound. |
