Do not lay, place, or throw field wire on or near power lines or transformers. Dangerous high voltages exist at these structures and severe shock or DEATH may result from contact between field wire and power lines. Follow the five emergency steps for electric shock. Be careful when using the TA-312/PT during storms. Lightning may pose a shock hazard.
90 to 100 volts DC may be present on the field wire terminals of the TA-312/PT. Don't take chances.
Adequate ventilation should be provided while using TRICHLOROTRIFLUOROETHANE. Pro longed breathing of vapor should be avoided. The solvent should not be used near heat or open flame; the products of decomposition are toxic and irritating. Since TRICHLOROTRIFLUOROETH ANE dissolves natural oils, prolonged contact with skin should be avoided. When necessary, use gloves which the solvent cannot penetrate. If the solvent is taken internally, consult a physician immediately.
