APPENDIX

CAUTIONARY PLACARD/NOTICE

Carcinogenic dye intermediates

1. Dye intermediates which are nitro amino derivatives or aromatic hydrocarbons are toxic. You have to handle these chemicals frequently in this factory.

2. Use the various items of protective wear to safeguard your own health.

3. Maintain scrupulous cleanlines at all times. Thoroughly wash hands and feet before taking meals.It is essential to take a bath before leaving the factory.

SCHEDUEL XXIII

Perations involving High Noise Levels

Application-

This schedule shall apply to all operations in any manufacturing process having high noise level.

Definition-

For the purpose of this schedule-

(a) "Noise" means any unwanted sound.

(b) "High Noise Level" means any noise level measured on the A weighted scale is 90 db or above.

(c) "Decibel" means one-tenth of "Bel" which is the fundamental division of a logarithmic scale used to express the ratio of two specified or implied quantities, the number of "Bel" denoting such a ratio being the logarithm to the base of 10 of this ratio. The noise level (or the sound pressure level) corresponds to a reference pressure of 20 x 10 = 6 newtons per square meter or 0.0002 dynes per square centimeter which is the threshold of hearing, that is, the lowest sound pressure level necessary to produce the sensation of hearing in average healthy listeners. The decibel in abbreviated form is db.

(d) "Frequency" is the rate of pressure variations expressed in cycles per second or hertz.

(e) "dba" refer to sound level in decides as measured on a sound level meter operating on the A-weighting net work with slow meter response.

(f) "A-weighting" means making graded adjustments in the intensities of sound of various frequencies for the purpose of noise measurement, so that the sound pressure level measured by an instrument reflects the actual response of the human ear to the sound measured.

Protection against noise--

(1) In every factory, suitable engineering control or administrative measures shall be taken to ensure, so far a is reasonably practicable, that no worker is exposed to sound levels exceeding the maximum permissible noise exposure levels specified in Tables 1 and 2.

TABLE-1

Permissible Exposure in Cases of Continuous Noise

Notes.

1. No exposure in excess of 1156 BA is to permitted.

For any period of exposure failing in between any figures and the next higher or lower figure as indicated in column 1, the permissible sound pressure level is to be determined by the extrapolation on a proportionate basis.

TABLE - 2

Permissible Exposure Levels of Impulsive or impact Noise

Notes

1. No exposure in excess of 140 dB peak sound pressure level is permitted.

2.

(1) For any peak sound pressure level failing in between any figure and the next higher or lower figure as indicated in column 1, the permitted number of impulses or impacts per day is to be determined by extrapolation on a proportionate basis.

(2) For the purposes of this Schedule, if the variations in the noise level involve at intervals of one second or less the noise is to be considered as a continuous one and the criteria given in Table 1, would apply. In other cases, the noise is to be considered as impulsive of impact noise and the criteria given in Table 2 would apply.

(3) When the daily exposure is composed of two or more periods of noise exposure at different levels their combined effect should be considered, rather than the individual effect of each. The mixed exposure should be considered to exceed the limit value if the sum

of the fractions C1 +C2..................Cn exceeds unity-

-------------------------------

T1+T2.................. Tn

Where the C1' C2 etc. indicate the total time of actual exposure at a specified noise level and TI, T 2 etc. denote the time of exposure permissible at that level. Noise exposure of less than 90 dBA may be ignored in the above calculation.

(4) Where it is not possible to reduce the noise exposure to the levels specified in sub-rule (1) by reasonably practicable engineering control or administrative measures, the noise exposure shall be reduced to the greatest extent feasible by such control measures, and each worker so exposed shall be provided with suitable ear protectors so as to reduce the exposure to noise to the levels specified in sub- rule (1 ).

(5) Where the ear protectors provided in accordance with sub-paragraph (2) and worn by a worker cannot still attenuate the noise reaching near his ear, as determined by subtracting the attenuation value in dBA of the ear protectors concerned from the measured sound pressure level, to a level permissible under Table 1 or Table 2 as the case may be, the noise exposure period shall be suitably reduced to correspond to the permissible noise exposures specified in sub- paragraph (1).

(6)

(a) In all cases where the prevailing sound levels exceed the permissible levels specified in sub-paragraph (1) there shall be administered an effective hearing conservation program which shall include among other hearing conservation measures, pre-employment and periodical auditory surveys conducted on, workers exposed to noise exceeding the permissible levels, and rehabilitation of such workers either by reducing the exposure to the noise levels or by transferring them to places where noise levels are relatively less or by any other suitable means.

(b) Every worker employed in areas where the noise exceeds he maximum permissible exposure levels specified in sub-rule (1) shall be subjected to an auditory examination by a Certifying Surgeon within 14 days of his first employment and thereafter, shall be re-examined at-last once in every 12 months. Such initial and periodical examinations shall include tests which the Certifying Surgeon any consider appropriate, and shall include determination of auditory threshold for pure tones of 125,250,500,1000,2000,4000 and 8 00 cycles per second.
