USE OF CHEMICALS. STORAGE AND HANDLING
There are various accidents and problems encountered in the actual foam production, and the production of each accident is caused by many factors.
Very often, the problems and failing in obtaining good quality is given by the use of chemicals, storage and handling the chemicals.
SET OF GOOD PRACTICES ON HOW TO AVOID MISTAKES AND ERRORS
CHOOSE THE RIGHT CHEMICALS
- We strongly advice you to consult and buy chemicals from specialized distributors, who don’t only sell you substances but also support you with all necessary knowledge, experience and good practice.
- Choose strong gelling catalyst, silicone surfactant.
USE OF CHEMICALS
- Always read the label on the drum of chemicals before taking or opening the drum for usage. Use chemicals before their expiry date.
PROCESS
- Check, adjust and finetune the formulation with box tests before launching it on the machine.
- Recommended to calibrate all pumps prior to foam production to determine the output and adjust.
- Clean inline filters/strainers and injector nipples on schedule.
- Replace malfunctioned 3-way control valve which redirect flow of chemicals.
- Place desiccant beds silica gel inside tank vent pipe.
STORAGE AND HANDLING
- Store the chemicals properly. Any balance of chemicals or unused chemicals must be discharged or kept airtight drums / container. Keep similar chemicals in one location within the store.
- Clearly label all storage and utility containers with distinct marks and keep them closed. Follow chemical storage guidelines from manufacturer such as keeping chemicals in protected, vented, cool, dry place.
- Follow correct procedures on storage, handling and disposal of chemical spillage. Use clean dry utility drums/container to measure, blend or transfer chemicals.
TRAINED PEOPLE
- Train all foaming assistants on how to handle chemicals.
- Wash hands or change hand gloves after handling every chemical.
