Unformatted text preview: dards for minimum and maximum brightness, temperature and relative
humidity. However if employees are exposed to harsh environmental conditions, working
time should be reduced so as not to pose a health hazard. In short, environmental
standards should suit the situation, and should be kept under constant review. Establish standards for lighting, temperature and humidity
4. Lighting. While lighting requirements for places such as inspection locations may be as
much as 640 lux or more, it is more common to simply specify “appropriate lighting”
and set suitable lighting levels for each area. Within a given room set the lighting levels
with reference to the main working area, since brightness may vary greatly. (Lux is a unit
of illumination equal to 1 lumen per square metre.)
5. Temperature. Temperature control is a very important factor in keeping workplaces
comfortable. Temperature levels should be set to provide a comfortable working
environment. Limit working time in extreme environments, such as steel mills or freezers.
Apart from special cases however, it is not critical to specify the temperature range. Unit 6 - Hygiene and Health 14 A Roadmap to Quality 05-87581_unit 6.qxd 01/08/2006 10:52 Page 15 6. Humidity. While humidity is recognised as an important element in health, appropriate
humidity levels are usually not specified in numeric terms, except for special types of
work. Normally it is left to nature to determine humidity levels. Variations due to
seasonal differences, such as the wet and dry seasons, and to the location, are not
unusual. However it is important to prevent excessive humidity or dryness, since these
can damage health. Discussion
The following questions ask you to think about how the ideas in the text could be applied in
your company. Some of the ideas may not be relevant to you. Concentrate on those that are
relevant. Keep notes of your conclusions – you will need them to prepare your action plan
afterwards. Where appropriate ask yourself the RADAR questions.
Note: Always include in your discussion any figures referred to in the text if you feel these
are relevant to your company.
a. Parag. 1: How comfortable and healthy is your workplace? Where do any problems
lie in terms of the factors mentioned here? How would you define a healthy
b. Parag. 2: Are there any special factors that make your workplaces unhealthy or
uncomfortable? What solutions could be found for these?
c. Parag. 3: Do you agree with the ideas in this paragraph. Does your company reduce
hours that employees have to spend in an unhealthy environment? If not, should it
d. Parags 4, 5 and 6: What acceptable levels for the factors of brightness, temperature
and humidity would you specify in standards? In other factors? (Noise odour and
vibration will come in Text 9.4.)
e. Discuss specific steps that should be taken to ensure that lighting, temperature and
humidity are at appropriate levels throughout your company. How cost-effective
would this be in terms of improvements in productivity, employee morale etc.? Action plan
Prepare an action plan for Texts 6.3 and 6.4 together after you have discussed Text 6.4.
Alternatively you may choose to prepare one action plan when you have discussed other
texts as well. You might like to use the 6-Point Structure. A Roadmap to Quality 15 Unit 6 - Hygiene and Health 05-87581_unit 6.qxd 01/08/2006 10:52 Page 16 6.4 Keep down noise, odour, vibration,
1. A healthy, comfortable environment must have low levels of noise, odour, vibration, and
airborne particles (dust). Establish standards for procedures to keep these down. Keep in
mind too that products and tools should be stored in suitable environmental conditions. Noise
2. Design and insulate noisy workplaces, so that employees in adjacent work areas will not
hear the noise. For example, when adjusting an engine, work should be performed in
an insulated, soundproof room, with the door tightly closed and employees wearing ear
protection. Do not keep the same employees in a noisy workplace for lengthy periods
of time. Odour
3. Take the following measures to reduce odours:
a. Fix odour-eliminating filters to all equipment that produces odour.
b. Pass any gas produced in a chemical reaction room through set filtering systems
before releasing it.
c. Filter all gas prior to releasing it outside the facility and check the filters regularly. Vibration
4. Take the following measures to limit vibration to the human body:
a. Include vibration damping in planning the layout of the workplace.
b. Put in vibration-damping equipment when installing large presses, and isolate them
from the rest of the workplace. Verify that the vibration caused by the press does not
escape the room.
c. Install equipment to limit vibration in areas where work causes vibration.
d. Install vibration meters around the facility and record the vibration level.
e. Regularly check the results of vibration damping since employees at other jobs ma...
