CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

RISK

Harmful by inhalation, in contact with skin and if swallowed.
Irritating to eyes and skin.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual.  Subchronic exposures to mono-, di- and tri- and tetra-substituted organotin compounds may elicit toxic response in the central nervous, immune and renal systems, the liver and bile duct and the skin.  Thioglycolate salts may produce decreased blood sugar levels, central nervous system depression, labored breathing, and convulsions.  

EYE

  This material can cause eye irritation and damage in some persons.  

SKIN

  Skin contact with the material may be harmful; systemic effects may resultfollowing absorption.  This material can cause inflammation of the skin oncontact in some persons.  The material may accentuate any pre-existing dermatitis condition.  Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.  

INHALED

  Inhalation of dusts, generated by the material, during the course of normalhandling, may be harmful.  The material is not thought to produce respiratory irritation (as classified using animal models). Nevertheless inhalation of dusts, or fume, especially for prolonged periods, may produce respiratory discomfort and occasionally, distress.  The acute toxicity of inhaled organotin compounds resembles that foundby other means of exposure.  

CHRONIC HEALTH EFFECTS

  Long term exposure to high dust concentrations may cause changes in lung function i.e. pneumoconiosis; caused by particles less than 0.5 micron penetrating and remaining in the lung. Prime symptom is breathlessness; lung shadows show on X-ray.  Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems.  Chronic occupational exposure to thioglycolate salts has produced allergic reactions such as, collection of fluid under the skin, burning of the skin, reddening and hemorrhage under skin surface, eczema like dermatitis of the scalp or hands and bleeding under the skin.
