Hey all, this is gary crawn from new paltz central school district. I am trying to get info on what your garages are using for clean-up on the buses for vomit and body fluid spills. currently I am using ZEP's chlor-retain, and it has been brought to my attention that according to the MSDS sheet, it is known to cause cancer. it is a light powdery substance that stays in the environment for a period of time. I am looking for a safe alternative to use while the kids are still on the bus as a measure of containing the spill until it can be cleaned. thank you all for your help.

MSDS
"Long term exposure to crystalline silica (an ingredient also found in many mineral deposits, soils and sand) has been known to cause silicosis,
a sometimes fatal lung disease, indicated by a dry cough and a gradual decrease in breathing ability. NTP and IARC classify respirable
crystalline silica as carcinogenic to humans when exposure levels exceed the PEL or TLV for extended periods of time."

PEL: Permissable Exposure Limit-"Some of the PELs are listed as ceiling values – concentrations above which a worker should never be exposed, or short-term exposure limits (STELs) –average concentrations which should not be exceeded over a 15 minute time period."
-http://www.ehs.wisc.edu/chem/OccupationalExposureLimits.pdf

TLV: Threshold Limit Value; based off 40hrweek, 8hr days "Short-term exposure limits (TLV-STEL) which are concentrations above which a worker should not be
exposed (averaged over 15 minutes). Exposures cannot be repeated more than 4 times per day "
-http://www.ehs.wisc.edu/chem/OccupationalExposureLimits.pdf

Long term exposure, as in use everyday and dust is flying everywhere and you breathe it... OFTEN.

What is crystalline silica?
"Crystalline silica is a basic component of soil,
sand, granite, and many other minerals. Quartz
is the most common form of crystalline silica.
Cristobalite and tridymite are two other forms
of crystalline silica. All three forms may become
respirable size particles when workers chip, cut,
drill, or grind objects that contain crystalline silica."
-https://www.osha.gov/OshDoc/data_General_Facts/crystalline-factsheet.pdf

-VOC's from aerosol cans (disinfectants/cleaners), exhaust fumes, and other inhale-able cleaners would be more of a 'concern' to drivers/students.

If you are in the a construction business of Sand blasting, or working in a concrete factory I would be much more concerned with crystalline silica (Ie. dust EVERYWHERE).

Gary,

If this was CA, everything is known to cause cancer.
