10 STABILITY AND REACTIVITY
Stable.
Do not store in aluminium or galvanised containers. Store away
from acids. Once Off is a caustic product which attacks soft
metals such as aluminium and zinc.
Hazardous polymerization: None.
11 TOXICOLOGICAL INFORMATION
Health Effects:
Acute:
Considered to be corrosive by all
exposure routes.
Swallowed: Can kill if swallowed. Because of its high alkalinity
in the undiluted state, Once Off is corrosive to the gastro-
intestinal tract if swallowed.
Skin: Principal route of exposure is usually by skin contact.
Corrosive to the skin on contact. Skin contact may cause
swelling, redness, blistering, dermatitis or burns with deep
ulceration and gelatinous necrotic areas at the site of contact.
Skin contact may result in little pain, thus care should be
taken to avoid contamination of gloves and boots.
Eye: Corrosive to the eyes on contact. Contamination of the
eyes can result in conjunctivitis and corneal burns and
ulceration which can result in permanent injury and possible
loss of sight.
Inhalation: Inhalation risk is low if product is used as directed,
but breathing of concentrated vapour should be avoided
because of risk of respiratory irritation.
Health Effects -
Chronic:
Repeated skin contact will cause
burns.
Toxicity data: Not available for mixture.
Sodium hydroxide : oral lowest lethal dose (rabbit) 500 mg/kg
(10% solution) Low systemic toxicity.
Triazole inhibitor: by ingestion: oral rat LD50 = 965m g/kg.
(Note: this data is from published information. Agar Cleaning
Systems does not carry out animal tests).
12 ECOLOGICAL INFORMATION
Ecotoxicity: Toxic to aquatic organisms.
Persistence and degradability: The surfactants in Once Off are
readily biodegradable.
Mobility: -
Advice: Product disperses in water. Avoid contaminating
natural waterways.
13 DISPOSAL CONSIDERATIONS
For disposal, refer to State Land Waste Management authority.
Empty containers must be decontaminated. Once Off can be
greatly diluted or carefully neutralised with dilute acid and
flushed to drain with copious amounts of water.
