INFORMATION
Mr. Hashimoto, President of HS-TECH ENGINEERING Co., Ltd. will deliver two presentations on Thai chemicals regulations in Tokyo, particularly he is thinking of focousing too much on core elements of Risk Assessment (RA) Methods whose system will be applied both existing chemicals and new chemicals which have fallen under some criteria, designated by the Department of Industrial Works (DIW).
The core elements of the RA are;
1) Priority List
2) Toxic List
3) Hazard score
4) Exposure score
5) Persistence/Bioaccumulation Score
6) Hazard assessment value
7) High risk substance
8) Concern of Risk
Portion of the Hazard Score
| Hazard Score | |||
| High-3 | Moderate-2 | Low-1 | |
| c) Mutagenicity/Genotoxicity | |||
| GHS hazard categories for germ cell mutagens | GHS category 1A, 1B | Positive in vivo or in vitro | Negative |
| GHS category 2 | |||
| d) Reproductive Toxicity | |||
| GHS hazard categories for reproductive toxicants | GHS category 1A, 1B | GHS category 2 | Non-specific secondary |
| consequence of reproduction | |||
| TSCA Work Plan Chemicals: Method Document 2012 | |||
| Oral (mg/kg/day) | <50 | 50-250 | >250 |
| Dermal (mg/kg/day) | <100 | 100-500 | >500 |
| Inhalation (gas/vapor) (mg/L/day) | <1 | 1-2.5 | >2.5 |
| Inhalation (mist/dust) (mg/L/day) | <0.1 | 0.1-0.5 | >0.5 |
The Risk Assessment Procedure might require importers / manufacturers to conduct human and environmental risk assessment through the core elements and to prepare risk assessment report.
Two times of session for one and half hour seminar, organized by a publishing company will be held in the afternoon of April 13.
