| Safety measures when working on vehicles with air conditioning system and when using refrigerant R 134a |
WARNING | It is recommended to hold an eye bath flask within reach. If liquid refrigerant gets into the eyes rinse the eyes out with water for approximately 15 minutes. |
| Subsequently apply eye drops and immediately contact a physician, even if the eyes are not painful. The physician must be informed that the frostbites were caused by refrigerant R134a. |
| The physician must be informed that the frostbites were caused by refrigerant R134a. If in spite of these safety measures refrigerant comes into contact with other body parts, rinse immediately with water for at least 15 minutes. |
| If in spite of these safety measures refrigerant comes into contact with other body parts, rinse immediately with water for at least 15 minutes. |
| Work on the air conditioning refrigerant circuit must only be carried out in well-ventilated areas. Switch on all available workshop exhaust systems. |
| Refrigerant must not be stored in lower areas (e.g. cellars) or related exits or window openings. |
| During paint repairs, the temperature of the objects placed in the drying oven or in its pre-heating zone must not exceed max. 80 °C (because heating causes a strong overpressure in the system that may result in the opening of the pressure relief valve). |
| Never fill the containers completely with liquid refrigerant. With sufficient expansion space (gas blanket) the container will burst as the temperature rises with catastrophic consequences. → Chapter. |
| Refrigerant containers (e.g. filling cylinders at the service position) must never be heated considerably or be exposed to direct sunlight see → Chapter. |
| Under no circumstances should refrigerant be filled into systems and reservoirs in which there is air (evacuate systems and reservoirs before filling with refrigerant). |
