SECTION 5 – HEALTH HAZARDS AND FIRST AID
WARNING! Wood dust may form an explosive mixture with air. Use exhaust ventilation when cutting, sawing or grinding in an
enclosed area. Wood dust may cause irritation to eyes, skin and upper respiratory tract. When cutting, sanding or grinding avoid
inhalation and wear safety glasses. Handling may cause splinters, use puncture resistant gloves. Do not burn pressure-treated
wood in open fire, stoves, fireplaces or residential boilers. Observe good hygiene and safety practices when handling this product.
Signs and Symptoms of Acute Overexposure First Aid Measures
Eyes: Wood dust may cause irritation to the eyes. Symptoms can include
irritation, redness, scratching of the cornea and tearing
Immediately flush eyes with water for
at least 15 minutes. Seek medical
attention if symptoms persist.
Skin: Prolonged contact with treated wood and/or treated wood dust may
cause irritation to the skin. Any wood dust may cause irritation to the
skin. Mechanical rubbing may increase skin irritation. Some wood
species and their dusts may contain natural toxins, which may cause
dermatitis or allergic reactions in sensitized individuals.
For skin irritation, flush immediately
with soap and water; continue at least
15 minutes. If irritation persists, get
medical attention immediately. If
wood splinters are injected under the
skin, get medical attention.
Ingestion: If ingestion does occur, slight gastrointestinal irritation may result.
Certain species of wood and their dusts may contain natural toxins,
which can have adverse effects on humans.
If the material is swallowed, get
medical attention or advice. Do not
induce vomiting.
Inhalation: Wood dust is irritating to the nose, throat and lungs. Symptoms may
include nasal dryness, deposits or obstructions in the nasal passages,
coughing, sneezing, dryness and soreness of the throat and sinuses,
hoarseness and wheezing. Prolonged or repeated inhalation of wood
dusts may cause respiratory irritation, recurrent bronchitis and
prolonged colds. Some species may cause allergic respiratory
reactions with asthma-like symptoms in sensitized individuals.
Prolonged exposure to wood dust by inhalation has been reported to
be associated with nasal and paranasal cancer.
If dusts are inhaled, remove person to
fresh air. If symptoms persist, seek
medical attention.
Note to Physician: Respiratory ailments and pre-existing skin conditions may be aggravated by exposure to wood dust. Medical
conditions generally aggravated by exposure to wood dust include pre-existing eye, respiratory and skin conditions.
Chronic Overexposure: Wood dusts may be irritating to the eyes, skin and respiratory tract. Prolonged or repeated inhalation of
wood dust may cause respiratory irritation, recurrent bronchitis and prolonged colds. Depending on the species of wood, recurrent
exposure may cause allergic skin and respiratory reactions in some individuals.
Carcinogenicity: ProWood Micro CA treated wood and its components, other than wood dust, are not listed as carcinogens by
ACGIH, NIOSH, of IARC. Wood dust is classified as a carcinogen by ACGIH, NIOSH, and IARC, which is based on an increased
incidence of nasal and paranasal cancer in people exposed to wood dusts. Carcinogenicity of wood dust: ACGIH – A1 Confirmed
Human Carcinogen (related to wood dusts-hard wood; NIOSH – Occupational carcinogen (related to wood dust); IARC --
Monograph 62, 1995 (related to wood dust)(Group 1 (carcinogenic to humans)). IARC has listed formaldehyde as a probable
human carcinogen.
SECTION 6 – EXPOSURE CONTROL MEASURES/PERSONAL PROTECTION
Personal Protective Equipment
Eyes/Face: Wear safety glasses with side shields when handling, cutting, sanding or grinding this material.
Use a face shield for processes that may generate excessive dusts and splinters.
Skin: Wear puncture resistant work gloves, such as leather when handling. Wear chemical resistant
rubber gloves when handling freshly treated lumber at the treating facility.
Respiratory: Respirators must be worn if the ambient concentration of airborne contaminants exceeds
prescribed exposure limits. Dust masks may be worn to avoid inhalation of nuisance dust. Dust
masks may not be adequate protection in environments above the occupational exposure limit.
Ventilation: Cutting, grinding or sanding should be done outdoors or in a well ventilated area.
