Pro duction and diffusion of smoke, fumes and gas of this nature should be prohibited as far as possible and their removal should be ensured by exhaust ventilation installed as near as possible to the point of production. Such smoke, fumes and gas-should be rendered harmless prior to being passed into the outside air. XXXVII In workrooms in which, in spite of all precautions taken, asphyxiating toxic or irritant fumes and gas may escape, the air renewal should be such th a t the workers' health does not suffer. XXXVIII No worker should be allowed to enter without protective apparatus places likely to contain toxic asphyxiating, or inflsiminable fumes or gas, until it has been ascertained that there is no risk. During work in closed apparatus and enclosed or partially enclosed spaces, where there is reason to apprehend the prcscnco of dangerous gas or fume or an irrespirable atmosphere, approved masks or oxygen breathing apparatus should be provided and worn by the workers. Safety belts with ropes attached should also be provided and used, and wherever possible at least one person should supervise from the outside the worker or workers exposed to danger. XXXIX Dust Escape of dust in workrooms or adjacent premises should bo avoided. During manipulation of dust-producing material, or manual or mechanical work causing dust liable to injure the health, requisite measures should bo taken to prevent dispersion of such dust in the air of the workroom. XL Mechanical processes accompanied by liberation of dust should as far as possible be carried on in closed apparatus, provided with exhaust devices. in Ucmi:;-. ol ; ' . i i i (aoiliu-i. i u c . n j ^ o a c <i ^ provided to capture the dust as close to its point ft o-igu possible.

Conditions in regard thereto should be laid down by the competent authority. 1 Large Furnaces X L II In industries or trades where the nature of the work necessi tates the use of glowing furnaces, measures should be taken to prevent workers in other departments of the establishment from being exposed to their action. X L III Fireproof screens for protection from heat and, where neces sary, fireproofsuits or articles of clothing, and also glasses affording protection against harmful radiation, should be placed a t the disposal of the workers directly exposed. XLIV Air renewal in workrooms should be such that high tempera ture does not injure the workers' health. LV Drying-Itooms, Stoves At no season should workers be made to entor drying-rooms and stoves when the interior temperature of these exceeds 503 C. (122 F.). Remaining in them continuously should be prohibited when the temperature" exceeds 35 C. (95'0 F.), Noise, Vibration, Shocks XLVI In noisy trades and in those in which tho running of machinery causes noise, shocks and marked vibration, every effort should be made to reduce as far as possible tho disagreeable effects.
