Other Preventive Measures

To keep dust concentration below recommended levels, processes should be enclosed &/or exhaust ventilation installed.
Adequate washing & ... sanitary facilities should be provided ... & rigorous personal hygiene measures should be encouraged. Smoking & consumption of food & beverages in workshops should be prohibited. Floors in workshops should be made of impermeable materials & frequently washed down.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. Ensure that the local ventilation moves the contaminant away from the worker.
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
If material not on fire and not involved in fire: Keep sparks, flames, and other sources of igniton away. Keep material out of water sources and sewers. Do not use water. Cover all suspected material with dry sand or earth to prevent ignition until material can be permanently disposed of.
Personnel protection: Keep upwind. Avoid breathing dusts, and fumes from burning material.
