## 3 Hazards identification

| Dusts | Can form potentially explosive mixtures with air. |
| --- | --- |
| Melt | Hot melt can cause skin burns. |
| **First aid measures** |  |
| Inhalation | On occurrence of irritation by vapours during thermal processing: ensure supply of fresh air, if necessary seek medical attention. After inhaling product dust: ensure supply of fresh air. |
| Eye contact | Wash with copious water. |
| Skin contact | Cool molten polyamide on the skin with copious cold water. Do not pull solidified polyamide from the skin. Medical attention is required for skin burns caused by molten material. |
| **Fire-fighting measures** |  |
| Suitable extinguishing media | Water spray, foam, CO2, dry powder. |
| Special hazards during fire-fighting | In case of fire, the following can be released: carbon monoxide, carbon dioxide, nitrogen oxide, organic decomposition products. Under certain fire conditions, traces of other toxic products cannot be excluded. |
| Special protective equipment during fire-fighting | Wear suitable protective clothing |
| **Accidental release measures** |  |
| Personal precautions | On release of product dust, use dust mask. |
| Environmental precautions | Do not allow to enter the environment. |

## Safety data sheet

**Methods for cleaning up** Sweep up spilt material or vacuum clean and place in a suitable container for disposal. Avoid the formation of dust.

## 7 Handling and storage

**Handling** Avoid formation of dust. Provide adequate ventilation and dust extraction at the machine. In case of thermal processing, provide for extraction of the vapours or adequate ventilation.  
**Protection against fire/explosion** Observe usual fire prevention measures. If dust is produced: take measures against electrostatic charge and keep away from sources of ignition.  
**Storage** No special measures required.

## 8 Exposure controls/personal protection

### Ingredients with occupational limits to be monitored

General dust limit: 6 mg/m³ MAC (Minimum Alveolar Concentration) (TRGS 900): alveolar fraction for activities/working areas as per No. 2.4 para. 8 and 9 in conjunction with paragraph 10 of TRGS 900.  
3 mg/m³ MAC (TRGS 900) alveolar fraction otherwise  
10 mg/m³ MAC (TRGS 900) inhalable fraction otherwise, from 1.4.2004 (in conjunction with number 2.4 para. 11 of TRGS 900)

### Technical protective measures

Provide extraction of vapours or adequate ventilation during thermal processing. On production of dust, provide adequate extraction.

## Personal protection equipment

**Industrial hygiene** Do not inhale dusts.  
**Respiratory protection** Required on production of dusts.  
**Hand protection** If this powder is handled at room temperature, it is not necessary to wear protective gloves. During thermal processing, thermally insulated protective gloves are to be used. Areas of the skin soiled with dust are to be cleaned with water and soap without delay, as the powder draws the natural moisture from the skin. Use barrier cream regularly.  
**Eye protection** Safety glasses recommended.

## 13 Disposal considerations

### Product

Observe local regulations, e.g. dispose of in a waste incineration plant. It is not possible to define a waste code number as per the European list of wastes, as allocation is only possible on definition of the purpose by the user. The waste code number is to be defined as per the European list of wastes (EU decision as regards the list of wastes 2000/532/EC) in consultation with the disposer/manufacturer/the authorities.

## 14 Transport information
