Chemical Analysis in the Laboratory: A Basic Guide

| Note | OES is occupational exposure standard and OEL is occupational exposure limit (based on HSE Guidance note EH40) |
Tox: = Toxicity
Pro: = Protection
Haz: Other known hazards
| Risks: | Can cause serious damage if splashed in eyes. Degreases skin, possibly causing dermatitis. Vapour narcotic in high concentrations. |
| Haz: | Extremely flammable. Reacts violently with chloroform and bromoform in the presence of alkalis or in contact with alkaline surfaces. Decomposes violently in contact with nitric/sulfuric acid mixtures. Can react violently with oxidising agents. |
| Tox: | LD50 5800 mg kg ?1 oral (rat). OES 2400 mg m ?3. |
| Pro: | Safety glasses. Nitrile gloves. Fume-cupboard. |
| Risks: | Irritating to eyes and if inhaled as dust. May irritate skin. |
| Haz: | Can ignite or explode in contact with strong oxidising agents. Finely divided materials can cause dust explosions. Can react violently with potassium and sodium metal. Mixtures with unsaturated oils can explode. |
| Tox: | No data. |
| Pro: | Rubber or plastic gloves. Good laboratory practice. |
| Risks: | Very toxic by ingestion, inhalation and skin contact. Extremely irritating to eyes and respiratory system. |
| Haz: | No data. |
| Tox: | May cause adverse mutagenic or teratogenic effects. LD50 160 mg kg ?1 oral (rat). |
| Pro: | Rubber or plastic gloves. Handle in a fume-cupboard. |
| Risks: | May be harmful by ingestion. Irritation to eyes and to respiratory system if inhaled as dust. |
| Haz: | No data. |
| Tox: | Evidence of mutagenic effects. OES Mo 5 mg m ? |
