What he said. There are 150,000 lawyers working for the government, and most of them are writing stupid regulations like these. I saw a MSDS once for latex paint that recommended disposing of all clothes you wear while applying it. Not cleaning, not ventilating, not disinfecting, not bleaching, but disposal. Asinine. Ever see one for sand? Here are some excerpts:

"CHRONIC INHALATION HAZARD.

AVOID PROLONGED OR REPEATED INHALATION OF DUST.

As part of good industrial and personal hygiene and safety procedure, avoid
all unnecessary exposure to the chemical substance and ensure prompt removal
from skin, eyes and clothing.

SPECIAL INFORMATION: In the event of a fire, wear full protective clothing
and NIOSH-approved self-contained breathing apparatus with full facepiece
operated in the pressure demand or other positive pressure mode.

Clean-up personnel may require respiratory protection from dust.

SPILLS: Sweep up and containerize for reclamation or disposal. Vacuuming or
wet sweeping may be used to avoid dust dispersal.

DISPOSAL: Whatever cannot be saved for reclamation may be delivered to an
approved waste disposal facility.

Ensure compliance with local, state and federal regulations.

INHALATION: Acute pneumoconiosis from overwhelming exposure to silica dust
has occurred. Coughing and irritation of throat are early symptoms.

EYE CONTACT: May irritate the eyes with redness, pain.

CHRONIC EXPOSURE: Repeated or prolonged inhalation of the dust particles
may cause silicosis. Symptoms may include a progressive dry cough, shortness
of breath and decreased chest expansion. If not treated, the disease may
progress with symptoms more severe.

AGGRAVATION OF PRE-EXISTING CONDITIONS: Inhalation may increase the
progression of tuberculosis; susceptability is apparently not increased.
Persons with impaired respiratory function may be more susceptible to the
effects of this substance. Smoking can increase the risk of lung injury.

INHALATION: Remove to fresh air. Get medical attention for any breathing
difficulty.

INGESTION: If large amounts were swallowed, get medical advice.

SKIN EXPOSURE: Wash exposed area with soap and water. Get medical advice if
irritation develops.

EYE EXPOSURE: Wash thoroughly with running water. Get medical advice if
irritation develops.

TOXICITY DATA (RTECS, 1986): No LD50/LC50 information found relating to
normal routes of occupational exposure. Tumorigenic Data Cited. Aquatic
Toxicity Rating: TLm 96: over 1000 ppm.

AIRBORNE EXPOSURE LIMITS:

OSHA Permissible Exposure Limit (PEL): 0.1 mg/m3 (TWA) respirable dust.

ACGIH Threshold Limit Value (TLV): 0.1 mg/m3 (TWA) respirble dust.

VENTILATION SYSTEM: A system of local and/or general exhaust is recommended
to keep employee exposures below the Airborne Exposure Limits. Local exhaust
ventilation is generally preferred because it can control the emissions of
the contaminant at its source, preventing dispersion of it into the general
work area. Please refer to the ACGIH document, "Industrial Ventilation, A
Manual of Recommended Practices", most recent edition, for details.

PERSONAL RESPIRATORS: (NIOSH APPROVED) If the TLV is exceeded, a dust/mist
respirator may be worn up to ten times the TLV. Consult respirator supplier
for details.

SKIN PROTECTION: Wear protective gloves and clean body-covering clothing.

EYE PROTECTION: Use chemical safety goggles. Contact lenses should not be
worn when working with this material. Maintain eye wash fountain and
quick-drench facilities in work area.

Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage."

So how do you feel about dragging your boat up on the beach? Damn stuff might catch fire, and there you are without your NIOSH-approved forced-air respirator. Oh, and your hollow shaft paddle is broken, too.
