Understand the process flow on how to manufacture the product. Identify the hazards from its process step (task). Decide who might be harmed and how. Evaluate the risks and decide on precautions. Record your findings and implement them 6. Review your assessment and update if necessary. Plastic Toys Production Process Flow: Fig: process flow of toys production

Fluid flow is an important part of most industrial processes; especially those involving the transfer of heat. Frequently, when it is desired to remove heat from the point at which it is generated, some type of fluid is involved in the heat transfer process. Examples of this are the cooling water circulated through a gasoline or diesel engine, the airflow past the windings of a motor, and the flow of water through the core of a nuclear reactor.
Bangladesh is one of the largest and biggest manufacturers of textile goods and materials over decades. Bangladesh has the world’s largest garment and textile manufacturer after China. After Coronavirus spreads all over the world from 2019 to 2021, the world market is changing dramatically. The apparel and fashion goods-making market is changing. Bangladesh has a total of more than 7000 industries in this sector. Bangladesh already achieved the world’s largest knitwear manufacturer country in the western marketplace.
In Apparel and Fashion industry, CM means Cost of Manufacture. In the garment manufacturing industry, CM means Manufacturing Cost of one dozen or 12 pcs garments. To calculate the CM of 12 pcs knit garments we must follow the below criterion-
monthly expenditure of the industry total no. of running machine machine qty to execute the layout of the specific order, productivity per shift dollar exchange rate Let, Monthly Industry Expenditure is BDT 80,00,000 Working days of the 30 days = 26 days Daily Factory Expenditure = BDT 307692.
