OCCUPATIONAL SAFETY & HEALTH STANDARDS

OCCUPATIONAL SAFETY & HEALTH STANDARDS
 (DEPARTMENT OF LABOR & EMPLOYMENT, PHILIPPINES, 1996)

1075: Illumination:

1075.01: General Provisions:

All places where persons work or pass or may have to work or pass in emergencies, shall be providedduring time of use with adequate natural lighting or artificial lighting or both, suitable for the operation andthe special type of work performed.

1975.02: Natural Lighting,

(1) Skylights and windows should be located and spaced so that daylight conditions are fairly uniformover the working area.

(2) Where necessary, skylights and windows should be provided with means to avoid glare.

(3) A regular system of cleaning skylights and windows should be established to ensure that they are keptclean at all times.

1075.03: Artificial Lighting:

Quality:

(1) Artificial lighting shall be provided when daylight fails or for area where the daylight illumination isinsufficient.

(2) The general lighting should be of uniform level, widely distributed to avoid harsh shadows or strongcontrast and free from direct or reflected glare.

(3) Where intense local lighting is necessary, a combination of general and supplementary lighting at thepoint of work may be provided.

(4) Supplementary lighting shall be specially designed for the particular visual task and arranged or provided with shading or diffusing devices to prevent glare.


1075.04: Intensity:

(1) Artificial lighting shall be adequate at the place of work for the operation or work performed.

(2) A minimum of 20 lux (2 foot candles) shall be provided for yards, roadways and outside thoroughfares.

(3) A minimum of 50 lux (5-foot candles) shall be provided:

a. where discrimination of detail is not essential, such as handling coarse materials, coal or ashes, roughsorting or grinding of clay products;

b. for passageways, corridors, stairways, warehouses, storerooms for rough and bulky materials.

38
 
(4) A minimum of 100 lux (1 0 foot candles) shall be provided:

a. where slight discrimination of detail is essential such as for the production of semi finished iron andsteel products, rough assembling, milling of grains, opening, picking and carding of cotton, or other primary operation in most of the industrial processes; and

b. for engine and boiler rooms, passenger and freight elevators, crating and boxing departments,receiving and shipping rooms, storerooms, and stockrooms for medium and fine materials, locker rooms,toilets, and washrooms.

(5) A minimum of 200 lux (20 foot candles) shall be provided where moderate discrimination of details isessential, such as for medium assembling, rough bench and machine work, rough inspection of testing of products, sewing light-colored textile or leather products, canning and preserving, meat packing, planingof lumber and veneering.

(6) A minimum of 300 lux (30 foot candles) shall be provided where close discrimination of details isessential such as for medium bench and machine work, medium inspection, fine testing, flour grading,leather finishing and weaving cotton goods or light colored cloth/goods or for office desk work withintermittent reading and writing for filing and mail sorting.

(7) A minimum of 500 to 1,000 lux (50 to 100 foot candles) shall be provided where discrimination of finedetails is involved under conditions of a fair degree of contrasts for long assembling, fine bench andmachine work, fine inspection, fine polishing and beveling of glass, fine wood-working and weaving darkcolored cloth/goods, or for accounting, bookkeeping, drafting, stenographic work, typing or other prolonged close office desk work.

(8) A minimum of I 000 lux (1 00 foot candles) shall be provided where discrimination of extremely finedetail is involved under conditions of poor contrast for long periods of time, such as for extra fineassembling instrument, jewellery, and watch manufacturing, grading and sorting tobacco products, make-up and proof-reading in printing plants, and inspection of sewing dark-colored cloth products.

(9) The provisions of paragraphs 2 to 8 apply to lighting equipment under average operating conditions.Where conditions allow, it may be necessary to provide initially an illumination of at least 25% more. Inlocations where dirt will collect rapidly, the initial level should be at least 50% above the recommendedstandards.

(10) Any windowless room shall be provided with general lighting sufficient in intensity for the mostexacting operations carried therein.

(11) Detailed standards of lighting intensity for different operations of work environment shall be asprovided in Table 8c.

Note: I foot candle = 10.75 lux

For purpose of computation use I foot candle = 10 lux

1075.06: Table of Illumination Levels:

Table 8c



1075.06: Emergency Lighting:

(1) Where large numbers of persons are employed in buildings more than one story in height, emergencylighting system shall be provided in all important stairways, exits, workplaces and passages.

(2) Emergency systems shall be capable of producing and maintaining for at least one (1)

hour, aminimum intensity of 5 lux (0.5 ft. candle) and shall have an energy source

independent of the generallighting system installation.

39
 
(3) Provisions shall be made for the automatic lighting of the emergency system immediately upon failureof the general lighting system.

Surface Resistivity Checker BOSCHSTAT BSC-SRM



BSC-SRM Surface Resistance Meter

BSC-SRM is an ultra wide-range, battery operated, portable instrument for measuring Surface Resistivity of virtually any flat surface conforming to ASTM D-257 standard by using recommended parallel bar sensing probe. In the circuit industry, products such as packaging materials, ESD shielding bags, work bench surfaces, static dissipative table and floor mats, conveyor belts, etc, have resistance values which need to conform to stringent specifications, Moreover, these values are expected to fall with in specified limits. The Surface Resistivity Meter can play a vital role in monitoring and checking the resistivity characteristic of the above items.
Specification:
Operating Temperature
0-50
Relative Humidity
0%-80% RH
Test Voltage
9 volts
Size
137(L)×76(W)×30(D)mm

Warranty
12 months
Accessories include
1m Grounding Cord & Carrying Leather Bag

It also has unique additional feature of surface-to-ground measurement capability wherein the resistivity differential between any surface and any chosen ground can be determined.

The surface resistivity is conveniently indicated by a row of LED’s covering a total of 10 decades from 103-1012 ohms per square.

Instruction to use:
Place the meter on the material to be tested and push the RED button in the middle of the unit. The unit measures the resistance between two electrodes on the back of the meter to determine surface resistivity, The LED that is lit, will indicate the surface resistivity in ohms per square.
Readings in Conductive Band
103= 1K Ohm
104= 10K Ohms
105= 100K Ohms

Readings in Insulating Band
1012= 1,000,000 Meg Ohms or greater

Readings in Static Dissipative Band
106= 1 Meg Ohms
107= 10 Meg Ohms
108= 100 Meg Ohms
109= 1,000 Meg Ohms
1010= 10,000 Meg Ohms
1011= 100,000 Meg Ohms

Resistance to ground measurement
Plug the stereo plug of the ground lead into the jack marked GROUND on the side of the meter. Connect the alligator clip to a suitable ground point for the material to the tested. For table mats, this will be generally be the snap for the mats ground cord. Place the meter in the desired location and push the RED test button. The unit will measure the resistance from the electrode on the right to the ground point. RTG values are measured in Ohms.
