■ Exposed individuals are reasonably expected to be warned, by smell, that the Exposure Standard is being exceeded.
Odour Safety Factor (OSF) is determined to fall into either Class A or B.
The Odour Safety Factor (OSF) is defined as:
OSF= Exposure Standard (TWA) ppm/ Odour Threshold Value (OTV) ppm
Classification into classes follows:
Class OSF Description
A 550 Over 90% of exposed individuals are aware by smell that the Exposure Standard (TLV-TWA for example) is being reached, even when distracted by working activities
B 26-550 As "A" for 50-90% of persons being distracted
C 1-26 As "A" for less than 50% of persons being distracted
D 0.18-1 10-50% of persons aware of being tested perceive by smell that the Exposure Standard is being reached
E <0.18 As "D" for less than 10% of persons aware of being tested
.

MATERIAL DATA

CLING ' N CLEAN TOILET BOWL CLEANER:
■ None assigned. Refer to individual constituents.
PHOSPHORIC ACID:
■ The saturated vapour concentration of phosphoric acid exceeds the TLV. The TLV- TWA is based by analogy from comparable experience and data for sulfuric acid.
Exposure at or below this limit is thought to prevent throat irritation amongst unacclimatised workers.
Fumes of phosphorus pentoxide at concentrations between 0.8 and 5.4 mg/m3 were reported to be noticeable but not uncomfortable whilst concentrations between 3.6 and
11.3 mg/m3 produced coughing in unacclimatised workers but were tolerable. Concentrations of 100 mg/m3 were unbearable except in inured workers.
CITRIC ACID:
■ It is the goal of the ACGIH (and other Agencies) to recommend TLVs (or their equivalent) for all substances for which there is evidence of health effects at
airborne concentrations encountered in the workplace.
At this time no TLV has been established, even though this material may produce adverse health effects (as evidenced in animal experiments or clinical experience).
Airborne concentrations must be maintained as low as is practically possible and occupational exposure must be kept to a minimum.
NOTE: The ACGIH occupational exposure standard for Particles Not Otherwise Specified (P.N.O.S) does NOT apply.
Sensory irritants are chemicals that produce temporary and undesirable side- effects on the eyes, nose or throat. Historically occupational exposure standards for
these irritants have been based on observation of workers' responses to various airborne concentrations. Present day expectations require that nearly every
individual should be protected against even minor sensory irritation and exposure standards are established using uncertainty factors or safety factors of 5 to 10 or
more. On occasion animal no- observable- effect- levels (NOEL) are used to determine these limits where human results are unavailable. An additional approach,
typically used by the TLV committee (USA) in determining respiratory standards for this group of chemicals, has been to assign ceiling values (TLV C) to rapidly
acting irritants and to assign short- term exposure limits (TLV STELs) when the weight of evidence from irritation, bioaccumulation and other endpoints combine to
warrant such a limit. In contrast the MAK Commission (Germany) uses a five- category system based on intensive odour, local irritation, and elimination half- life.
However this system is being replaced to be consistent with the European Union (EU) Scientific Committee for Occupational Exposure Limits (SCOEL); this is more
closely allied to that of the USA.
OSHA (USA) concluded that exposure to sensory irritants can:
· cause inflammation
· cause increased susceptibility to other irritants and infectious agents
· lead to permanent injury or dysfunction
· permit greater absorption of hazardous substances and
· acclimate the worker to the irritant warning properties of these substances thus increasing the risk of overexposure.
WATER:
■ No exposure limits set by NOHSC or ACGIH.

 

PERSONAL PROTECTION

EYE

· Chemical goggles.
· Full face shield may be required for supplementary but never for primary protection of eyes
· Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document, describing the wearing of lens or
restrictions on use, should be created for each workplace or task. This should include a review of lens absorption and adsorption for the class of chemicals in use
and an account of injury experience. Medical and first- aid personnel should be trained in their removal and suitable equipment should be readily available. In the
event of chemical exposure, begin eye irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at the first signs of eye redness
or irritation - lens should be removed in a clean environment only after workers have washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59], [AS/NZS
1336 or national equivalent].

HANDS/FEET

· Wear chemical protective gloves, eg. PVC.
· Wear safety footwear or safety gumboots, eg. Rubber.
· When handling corrosive liquids, wear trousers or overalls outside of boots, to avoid spills entering boots.

OTHER

· Overalls.
· P.V.C. apron.
· Barrier cream.
· Skin cleansing cream.
· Eye wash unit.
The local concentration of material, quantity and conditions of use determine the type of personal protective equipment required. For further information consult
site specific CHEMWATCH data (if available), or your Occupational Health and Safety Advisor.

ENGINEERING CONTROLS

■ Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well- designed engineering controls can be highly effective
in protecting workers and will typically be independent of worker interactions to provide this high level of protection.
The basic types of engineering controls are:
Process controls which involve changing the way a job activity or process is done to reduce the risk.
Enclosure and/or isolation of emission source which keeps a selected hazard " physically" away from the worker and ventilation that strategically " adds" and "
removes" air in the work environment. Ventilation can remove or dilute an air contaminant if designed properly. The design of a ventilation system must match the
particular process and chemical or contaminant in use.
Employers may need to use multiple types of controls to prevent employee overexposure.
General exhaust is adequate under normal operating conditions. Local exhaust ventilation may be required in special circumstances. If risk of overexposure exists,
wear approved respirator. Supplied- air type respirator may be required in special circumstances. Correct fit is essential to ensure adequate protection. Provide
adequate ventilation in warehouses and enclosed storage areas. Air contaminants generated in the workplace possess varying " escape" velocities which, in turn,
determine the " capture velocities" of fresh circulating air required to effectively remove the contaminant.
Type of Contaminant: Air Speed:
solvent, vapours, degreasing etc., evaporating from tank (in still air). 0.25-0.5 m/s (50-100 f/min)
aerosols, fumes from pouring operations, intermittent container filling, low speed conveyer transfers, welding, spray drift, plating acid fumes, pickling (released at low velocity into zone of active generation) 0.5-1 m/s (100-200 f/min.)
direct spray, spray painting in shallow booths, drum filling, conveyer loading, crusher dusts, gas discharge (active generation into zone of rapid air motion) 1-2.5 m/s (200-500 f/min.)
grinding, abrasive blasting, tumbling, high speed wheel generated dusts (released at high initial velocity into zone of very high rapid air motion) 2.5-10 m/s (500-2000 f/min.)
Within each range the appropriate value depends on:
Lower end of the range Upper end of the range
1: Room air currents minimal or favourable to capture 1: Disturbing room air currents
2: Contaminants of low toxicity or of nuisance value only. 2: Contaminants of high toxicity
3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in motion 4: Small hood-local control only
Simple theory shows that air velocity falls rapidly with distance away from the opening of a simple extraction pipe. Velocity generally decreases with the square of distance from the extraction point (in simple cases). Therefore the air speed at the extraction point should be adjusted, accordingly, after reference to distance from the contaminating source. The air velocity at the extraction fan, for example, should be a minimum of 1- 2 m/s (200- 400 f/min) for extraction of solvents generated in a tank 2 meters distant from the extraction point. Other mechanical considerations, producing performance deficits within the extraction apparatus, make it essential that theoretical air velocities are multiplied by factors of 10 or more when extraction systems are installed or used.

Section 11 - TOXICOLOGICAL INFORMATION

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

■ The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion.
The material has NOT been classified by EC Directives or other classification systems as " harmful by ingestion" . This is because of the lack of corroborating
animal or human evidence. The material may still be damaging to the health of the individual, following ingestion, especially where pre- existing organ (eg. liver,
kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality rather than those producing morbidity
(disease, ill- health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities
is not thought to be cause for concern.

EYE

■ The material can produce chemical burns to the eye following direct contact. Vapours or mists may be extremely irritating.
If applied to the eyes, this material causes severe eye damage.
The material may produce severe irritation to the eye causing pronounced inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.
Solutions of low- molecular weight organic acids cause pain and injuryto the eyes.

SKIN

■ The material can produce chemical burns following direct contactwith the skin.
Skin contact is not thought to have harmful health effects (as classified under EC Directives); the material may still produce health damage following entry through
wounds, lesions or abrasions.
The material may cause severe skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles,
scaling and thickening of the skin. Repeated exposures may produce severe ulceration.

INHALED

■ Not normally a hazard due to non- volatile nature of product.
The material has NOT been classified by EC Directives or other classification systems as " harmful by inhalation" nor has it been designated as " irritating to the
respiratory system" . This is because of the lack of corroborating animal or human evidence. In the absence of such evidence, care should be taken nevertheless to
ensure exposure is kept to a minimum and that suitable control measures be used, in an occupational setting to control vapours, fumes and aerosols.
High concentrations cause inflamed airways and watery swellingof the lungs with oedema.

CHRONIC HEALTH EFFECTS

■ Long- term exposure to the product is not thought to produce chronic effects adverse to the health (as classified by EC Directives using animal models);
nevertheless exposure by all routes should be minimised as a matter of course.

TOXICITY AND IRRITATION

■ unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
■ Asthma- like symptoms may continue for months or even years after exposure to the material ceases. This may be due to a non- allergenic condition known as reactive
airways dysfunction syndrome (RADS) which can occur following exposure to high levels of highly irritating compound. Key criteria for the diagnosis of RADS include
the absence of preceding respiratory disease, in a non- atopic individual, with abrupt onset of persistent asthma- like symptoms within minutes to hours of a
documented exposure to the irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to severe bronchial hyperreactivity on methacholine
challenge testing and the lack of minimal lymphocytic inflammation, without eosinophilia, have also been included in the criteria for diagnosis of RADS. RADS (or
asthma) following an irritating inhalation is an infrequent disorder with rates related to the concentration of and duration of exposure to the irritating substance.
Industrial bronchitis, on the other hand, is a disorder that occurs as result of exposure due to high concentrations of irritating substance (often particulate in
nature) and is completely reversible after exposure ceases. The disorder is characterised by dyspnea, cough and mucus production.

■ for citric acid (and its inorganic citrate salts) Based on many experimental data in animals and on human experience, citric acid is of low acute toxicity. The NOAEL for repeated dose toxicity for rats is 1200 mg/kg/d. The major, reversible (sub)chronic toxic effects seem to be limited to changes in blood chemistry and metal absorption/excretion kinetics. Citric acid is not suspected of being a carcinogen nor a reprotoxic or teratogenic agent. The NOAEL for reproductive toxicity for rats is 2500 mg/kg/d. Further, it is not mutagenic in vitro and in vivo. Also, the sensitising potential is seen as low. In contrast, irritation, in particular of the eyes but also of the respiratory pathways and the skin, is the major toxicological hazard presented by citric acid. The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin. WATER: ■ No significant acute toxicological data identified in literature search.

■ May cause long- term adverse effects in the aquatic environment. Do NOT allow product to come in contact with surface waters or to intertidal areas below the mean high water mark. Do not contaminate water when cleaning equipment or disposing of equipment wash- waters. Wastes resulting from use of the product must be disposed of on site or at approved waste sites. On the basis of available evidence concerning either toxicity, persistence, potential to accumulate and or observed environmental fate and behaviour, the material may present a danger, immediate or long- term and /or delayed, to the structure and/ or functioning of natural ecosystems. Ecotoxicity: The tolerance of water organisms towards pH margin and variation is diverse. Recommended pH values for test species listed in OECD guidelines are between 6.0 and almost 9. Acute testing with fish showed 96h- LC50 at about pH 3.5. The principal problems of phosphate contamination of the environment relates to eutrophication processes in lakes and ponds. Phosphorus is an essential plant nutrient and is usually the limiting nutrient for blue- green algae. A lake undergoing eutrophication shows a rapid growth of algae in surface waters. Planktonic algae cause turbidity and flotation films. Shore algae cause ugly muddying, films and damage to reeds. Decay of these algae causes oxygen depletion in the deep water and shallow water near the shore. The process is self- perpetuating because anoxic conditions at the sediment/water interface causes the release of more adsorbed phosphates from the sediment. The growth of algae produces undesirable effects on the treatment of water for drinking purposes, on fisheries, and on the use of lakes for recreational purposes. Prevent, by any means available, spillage from entering drains or water courses. CITRIC ACID:

■ for citric acid (and its inorganic citrate salts) Environmental fate: Due to its physico - chemical characteristics citric acid is highly mobile in the environment and will partition to the aquatic compartment. Citric acid is rapidly degraded in both sewage works and surface waters and in soil. Citric acid is exceedingly soluble in water, has relatively low acid dissociation constants that ensure that the substance is at least partly deprotonated in aqueous solution at all environmentally relevant pH values. Additionally, it has a low n- octanol/water partition coefficient; no precise information was found on vapour pressure but the melting point is around 153 deg C. The result of a QSAR estimation is 7.3 x 10- 7 Pa at 25 deg C. These properties of citric acid indicate that it is likely to partition mainly into the water phase, with very little distributing into the atmosphere. In addition, due to the high water solubility the substance is unlikely to adsorb onto soil or sediment. Using a level III generic fugacity model it is predicted that if citric acid is released to water, it is unlikely to partition into other environmental compartments. Release of citric acid to air is likely to lead to distribution into soil and water through deposition processes, while release or deposition onto soil is predicted to lead to redistribution into the aquatic compartment. The prediction of extensive and rapid degradation, both in sewage treatment plants and in natural water bodies, is borne out by experimental data confirming double to three times the degradation of low concentrations of citric acid in lake water at pH 8 as compared to in distilled water. Estimation of the indirect photolysis using a photochemical hydroxyl radical reaction constant of 7.02 x 10- 12 cm3/mol sec and assuming a hydroxyl radical concentration 0.5 x 106 OH/cm3 would result in an atmospheric half life of 2.3 days It should be kept in mind that environmental citrate concentrations do not only derive from man- made citric acid but that citric acid is extremely widespread in nature respectively widely distributed in plants and animal tissues and fluids and that every single eukaryote organism produces citric acid and excretes part of it to the environment. Environmental fate: Citric acid is of low acute toxicity to freshwater fish, daphnia and algae and also to the few marine species tested; longer - term tests show comparable effect values. Similarly, citric acid has no obvious toxic potential against protozoans and many species or strains of bacteria including activated sludge micro- organisms. Many results refer to toxic limit concentrations or no effect concentrations, from which no dependable EC50 can be derived. In a “long- term” daphnia test in “soft water”, which may be assumed not to buffer the acid effect of the test substance, the EC0 was found to be 80 mg/l and the EC100 was 120 mg/l, resulting in a geometric mean EC50 of 98 mg/l. Similarly, the lowest reported EC0 in cyanobacteria was 80 mg/l. Different strains of bacteria showed positive growth respectively good to excellent degradation with citric acid as the sole carbon source and the same holds for sewage sludge micro- organisms that thrive on citric acid. The few marine species for which data are available seem to be somewhat more sensitive to citric acid, although at 160 mg/l the only acute LC50 reported for a crab is over 100 mg/l, while for two algae and a protozoan the subacute toxic limit concentration is only given as a wide range between 1 and 300 mg/l. Still, at least for the few tested organisms citric acid does not seem to be highly or acutely toxic. The toxicity of citric acid to other environmentally relevant species has not been determined. Based on the available data, citric acid is not judged to be a substance that presents a hazard to the environment.
