Conducting Effective Drills
The following three steps are required for drills to be effective:
Plan the drill-effective drills should always be carefully planned to focus the training on a particular need. Planning the drills maximizes the benefits of conducting the drills and minimizes the amount of time wasted during the drill
Conduct the fire drill realistically – The drill should stimulate an actual condition and make the crew performing as though the actual emergency condition existed.
Conclude with a critique and discussion session immediately following the drill will identify the problem areas and point out mistakes while they are fresh in the minds of the crew.
Each drill should be designed to emphasize a single aspect of responding to an emergency, even though every drill should contain all the steps necessary in a real emergency. A single drill should not attempt to teach crewmembers everything at once. Focusing the drill on a single aspect simplifies the drill, can increase the chances of that aspect being remembered during an emergency if necessary, and keeps the time required for the drill within an acceptable limit.
Select a suitable location: The location for the drill should be appropriate for the aspect being emphasized. For example a drill that focuses on life raft deployment should beheld at a life raft station. The location for a fire or another emergency situation should vary from time to time.
Avoid undue risk: Drills should avoid exposing the crew installations to situations that may place them in jeopardy. For example toxic fumes should not be used when training crew members in the use of self- contained breathing apparatus or fires started to test fire fighting system.
The Person in Charge should avoid placing his crew in high risk situation,avoiding all risk should mild seaway can entail some risk, this risk can be reduced to an acceptable level with proper maintenance and training. The benefits of operating this equipment to increase the chance of successful deployment in a real emergency are high and therefore worthwhile. This type of drill should be conducted preferably in sheltered waters or in good weather condition with the minimum crew on board (3 men).The steps that should be taken after clearing the
platform vessel or module are discussed.These steps include:

Electric Resistance Heaters
Electric resistance heaters are used for heating the glue applied over the print blankets, which holds the fabric in place. When the belt finishes its movement on the upper side and when it moves down, the glue gets dried, which has to be heated again to retain its properties before it is exposed to the fabric again. In place of electric heaters if infra-red heaters are used, the efficiency would be better and energy consumption will be reduced.
Reduced electricity consumption of about 4 kWh/hour per infra-red heater.
Better work environment.
This option of Electric Resistance Heaters is a technology modification option for heating of the print blankets on continuous printing machines. This is a measure applicable to all printing machines that use print blankets (endless), which are coated with adhesives for holding the cloth in place while printing.
Investment cost per infra-red heater is Circuit Maintenance Process . Thus, annual savings are calculated to be INR 86 400 (USD 1 920) for operation of one infra-red heater, replacing three electric resistance heaters. Payback period is less than a month.
Pentachlorophenol by di-chlorophenol
Di-chlorophenol is less toxic than pentachlorophenol and can serve the purpose of a print paste preservative (used also as size preservative) and hence could be used in place of penta-chlorophenol. The measure would result in toxicity reduction.
Next to the working time of the employees involved in the project and installation of the instructions, no extra costs are associated with this measure.
Experience demonstrates a fast pay-back, due to adequate chemical handling by employees, accident prevention and appropriate waste management.
Reduced toxicity. Reduced fire hazards. Microbial growth in effluent treatment plant is not disturbed due avoidance of toxicity.
Applicable in the print paste preparation section of the textile printing industries.
Investment is same (because, it is just replacement of input material). Annual savings in monetary terms is negligible, but there are great environmental benefits along with the operational ease of the effluent treatment plant.

Automatic Self Closing Valve
- Automatic Self Closing Valve – The moment a burner turns off, a natural draft can develop through the boiler and the chimney. A valve on the chimney that automatically closes when the burner is turned off, keeps the hot air within the boiler.
- In case this measure is implemented, the boiler better maintains its temperature and pressure. Boiler pressure is maintained during the night and therefore the boiler can quickly be started in the morning.
- This option is profitable in case the boiler is turned off or on stand-by overnight.
- The investment costs for an automatic valve range between INR 30 000 and INR 60 000. When the boiler is turned off at night or left on stand-by, this option can have a payback period of two years.
- There is a tremendous amount of information on the Internet about boiler efficiency. For instance, have a look at the boiler efficiency database. It may be Gas cylinder valve
Measuring the wastewater generation
This option supports you in getting an overview of the amount and quality
of the wastewater generated in your company.
Wastewater treatment is an important cost-driver in textile processing
and a major source of environmental pollution. Collecting and generating data
about wastewater generation are thus key steps to improve your efficiency in
textile processing. The reasoning behind it is quite simple: “if you don’t
measure it, you can’t manage it”. Using the generated data will help you
to draw a trend line of your performance over different time-periods
(benchmark), to identify improvement options and to set targets. With a
benchmarking process you can compare your performance internally as well as
externally, with industry averages or competitors.
In order to determine the generated wastewater streams you can use the following table. Please determine the processes where the largest amount of wastewater occurs. In the case of wastewater, it is not only the amount but also the quality, which count. Where possible, state the generated amount and specify key characteristics1 of your effluent to get information on its quality. If available, use data from the last fiscal year or the last quarter and state the chosen time-period in the table. Otherwise collect the necessary information. Also try to fill out the total wastewater generated, which should not simply add up rows above, but summarise wastewater generated by all processes.
For comparability reasons make sure to use
the same time-period (e.g. one fiscal year) for all processes. In case you do
not have the information and/or cannot collect it, try to fill out the table
based on estimates. In this case, mention in the comments line that the figures
are estimates.
To benchmark your performance and see your improvements,
use a “wastewater generated per unit” ratio. The “unit” should be the unit of
production that is most useful for you. Examples could be “m2 of
product” or “1 000 units of product” (e.g. my company generates X m3
of wastewater for every 1 000 m2 of fabrics produced). You can also
use a ratio based on wastewater treatment costs per unit.
The management option Measure your water use efficiency is also an interesting option to
help you improving your wastewater generation. While this option targets your
water output, Measure your water use
efficiency helps you to control and reduce the water you put in your
processes, contributing directly to reduce your wastewater generation.
