6.3 Methods and materials for containment and cleaning up
SRP: Criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
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.
All waste must be handled in accordance with local, state and federal regulations.: Recycle wherever possible. Consult manufacturer for recycling options or consult Waste Management Authority for disposal if no suitable treatment or disposal facility can be identified. Dispose of by: Burial in a licensed land-fill or Incineration in a licensed apparatus (after admixture with suitable combustible material) Decontaminate empty containers. Observe all label safeguards until containers are cleaned and destroyed.
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. The completeness of the cleaning procedures should be considered before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at the 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.
Avoid all personal contact, including inhalation. Wear protective clothing when risk of exposure occurs. Use in a well-ventilated area. Prevent concentration in hollows and sumps. DO NOT enter confined spaces until atmosphere has been checked.
Do not allow material to contact humans, exposed food or food utensils. ... When handling, DO NOT eat, drink or smoke. ... Always wash hands with soap and water after handling.

12.1 Toxicity
/OTHER TERRESTRIAL SPECIES/ Under laboratory conditions, the comparative effects of two insect growth regulators, chlorfluazuron and oxymatrine, and spinosad as a biopesticide were examined on honey bee workers (Apis mellifera L.). Separate groups of bees were left for 24 hr to feed on 50% sucrose solution containing different concentrations of the tested insecticides, and the lethal concentration that caused 50% mortality (LC50) was estimated. The inhibitory effects on acetylcholinesterase (AChE) and adenosine triphosphatase (ATPase) activities as biochemical indicators were determined in vivo after 24 hr in head, thorax, and abdomen of surviving bees obtained after treatments with a view to explore the possible mode of action of these compounds. Results indicated that exposure to spinosad showed toxicity to honey bees with LC50 value of 7.34 mg/L, followed by oxymatrine (LC50 = 10.68 mg/L), while chlorfluazuron was the least acutely toxic of the tested compounds (LC50 = 2,526 mg/L). Oxymatrine and spinosad at the same tested concentrations (2.5, 5, 10, and 20 mg/L) significantly inhibited AChE activity in different organs of honey bee workers, and high inhibition percentage was obtained with the enzyme isolated from the thorax... addition, the toxic effects of the tested compounds on activity of ATPase indicated that spinosad caused the highest inhibitory effect in different organs compared with oxymatrine at the same concentrations, and high inhibition was found with ATPas
