Safety Data Sheets
The Hazard Communication Standard requires that all chemical manufacturers, distributors, or importers provide Safety Data Sheets (SDS) for each hazardous chemical. The SDS sheets (formerly Material Safety Data Sheets or MSDS) are designed to communicate information the product listed on the sheet. The SDS sheets are very simlar to MSDS sheets but are required to format in a consistent 16-section format. This makes the experience of reading these sheets easier on the user.The SDS sheets, which employers should have available to all employees, provide information on a variety of different areas including hazards, protective measures, and safety precautions. Sections 1 through 8 contain general information about the product including appearance, hazards, composition, etc. Sections 12 through 16 are designed to be part of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) but OSHA does not enforce these sections.
Below is a basic breakdown of each section and an example of what the section will look like in a completed SDS.

Thhe Globally Harmonized System of Classification and Labeling of Chemical Classification
With the rollout of the new The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) comes the rollout of new hazard classifications, pictograms, and explanations. As the system is introduced worldwide, new pictograms will be appearing across various manufacturers' products. Below is a basic explanation of the pictograms and their hazards. For more information, please visit one of the GHS resource links.
Hazard | Pictogram | Description |
---|---|---|
Explosives |
Explosives are labeled with one of six categories depending on the hazard. Categories are as follows:
|
|
Flammable Gases | A flammable gas is any gas that has a flammable range in air at 20°C and a standard pressure of 101.3 kPa. | |
Flammable Aerosols | Aerosols are considered flammable if any component in them is classified as flammable according to GHS. This can include flammable liquids, gases, or solids. | |
Oxidizing Gases | Oxidizing gases are gases that when mixed with oxygen, can cause the combustion of surrounding materials. Under normal circumstances these materials would be at the same risk when exposed to air. | |
Gases Under Pressure | Gases contained in a container with a pressure of more than 280 Pa at 20°C or as a refrigerated liquid are considered gases under pressure. This classification covers what can happen if the pressure is suddenly released or the container is frozen not the effects of the gas itself. | |
Flammable Liquids | A flammable liquid is any liquid with a flash point of not more than 93°C. | |
Flammable Solids | A flammable solid is a solid that is readily combustible or can cause or contribute to a fire because of friction. Solids can include powered, granular, or pasty substances which can ignite with even brief contact. | |
Self-Reactive Substances | A self-reactive substances are any thermally unstable liquids or solids that are liable to undergo a strongly exothermic thermal decomposition with or without oxygen. | |
Pyrophoric Liquids | A pyrophoric liquid is a liquid that can ignite within five minutes of coming in contact with air. This can happen with any amount of the liquid. | |
Pyrophoric Solids | A pyrophoric solid is a solid that can ignite within five minutes of coming in contact with air. This can happen with any amount of the solid. | |
Self-Heating Substances | A self-heating substance is a solid or liquid that is not pyrophoric, that can self-heat when brought into contact air. It does not need an energy supply to heat. | |
Substances which, in contact with water emit flammable gases | Substances for this category either emit flammable gases when in contact with water or are solid or liquids that are likely to spontaneously flammable or give off dangerous quantities of flammable gases when in contact with water. | |
Oxidizing Liquids | Oxidizing liquids themselves are not typically combustible but when producing oxygen, they can cause or contribute to the combustion of surrounding materials. | |
Oxidizing Solids | Oxidizing solids themselves are not typically combustible but when producing oxygen, they can cause or contribute to the combustion of surrounding materials. | |
Organic Peroxides | Organic Peroxides are organic liquids or solids that have the bivalent -0-0- structure. They may be considered derivative of hydrogen peroxide where one or more atoms have been replaced by organic radicals. | |
Corrosive to Metals | Any substance or mixture that by chemical action can damage or destroy metals are considered corrosive to metals. | |
Acute Toxicity | Acute toxicity is the adverse effects that occur after oral or dermal administration of a single dose of a of a substance. It also includes multiple doses with in 24 hours and inhalation exposure for 4 hours. | |
Skin Corrosion | Skin corrosion means irreversibly damage to the skin after application for up to four hours. | |
Skin Irritation | Skin irritation means that after application for up to four hours, any damage to the skin is reversible and not permanent. | |
Serious Eye Damage | Serious eye damage means that the production of tissue in the eye was damaged or a serious decrease in vision occurs after application of a substance to the front of the eye. This damage is not fully reversible within 21 days of application. These changes can be permanent. | |
Eye Irritation | Eye irritation are any changes in the eye that occur after a substance was applied to the front surface of the eye that are full reversible within 21 days. These changes are not permanent. | |
Respiratory Sensitization | Respiratory sensitization happens when a substance induces hypersensitivity of the airways after inhalation. Typically this makes breathing difficult. | |
Skin Sensitization | Skin sensitization means an allergic reaction like response occurs when a substance comes into contact with skin. This is also known as contact sensitization. | |
Germ Cell Mutagenicity | Germ cell mutagenicity means that a substance is causing an increased occurrence of mutations in populations of cells and organisms through exposure. | |
Carcinogenicity | Carcinogenicity means that a chemical or mixture is likely to cause cancer or increase the likelihood of getting cancer. | |
Reproductive Toxicology | Reproductive toxicology means that exposure to substances with this label can cause adverse effects on sexual function and fertility in both males and females. They can also cause developmental toxicity in offspring. | |
Target Organ Systemic Toxicity - Single and Repeated Exposure | All significant health effects that are not otherwise listed in the GHS classifications are considered Target Organ Systemic Toxicity. This includes anything that impairs function, is reversible or irreversibly, immediate or delayed, narcotic effects and respiratory tract irritation. This is also known as Specific Target Organ Toxicity. | |
Aspiration Toxicity | Aspiration hazard includes severe acute effects including chemical pneumonia, varying degrees of pulmonary injury, and death following aspiration. Aspiration is defined as the entry of a liquid or solid substance through oral or nasal cavities or indirectly through vomiting. | |
Hazardous to the Aquatic Environment |
• Acute - The substance caused injury to an aquatic organism during short-term exposure • Chronic - potential or actual properties of the substance will effects to aquatic organisms during exposure that are determined by the lifecycle of the organism. |

Lead Free Law
The Reduction of Lead in Drinking Water Act was enacted on January 4th 2011. It amends Section 1417 of the Safe Drinking Water Act (SDWA) and became effective January 4th, 2014. According to the EPA, this amendment can be broken down as follows:
- 1) Lower maximum lead content of the wetter surfaces of plumbing products such as pipes, pipe fittings, plumbing fittings, & fixtures from 8.0% to a weighted average of 0.25%.
- 2) Establish a statutory method of the calculation of lead content.
- For each wetted component the percentage of lead in the component is multiplied by the ratio of the wetted surface area of that component to the total wetted surface area of the entire product to arrive at the weighted percentage of lead of the component.
- The weighted percentage of lead of each wetted component is added together, and the sum of these weighted percentages constitutes the weighted average lead content of the product. The lead content of the material used to produce wetted components is used to determine compliance
- For lead content of materials that are provided as a range, the maximum content of the range must be used.
- 3) Eliminate the requirement that lead free products be in compliance with voluntary standards established in accordance with SDWA 1417 (e) for leaching of lead from new plumbing fittings & fixtures.
- 4) Create exemptions in SDWA section 1417 (a) from the prohibitions on the use or introductions into commerce for:
- Pipes, pipe fittings, plumbing fittings or fixtures, including backflow preventers that are used exclusively for non-potable services or other uses where the water is not anticipated for human consumption.
- Toilets, bidets, urinals, fill valves, flushometer valves, tub fillers, shower valves, service saddles, or water distribution main gate valves that are 2 inches in diameter or larger.
What's Affected? | What's Exempt |
---|---|
Brass ball valves Brass check valves Back flow preventers Angle stops Straight stops Cast brass copper fittings Threaded brass fittings Water main fittings Faucets Flux Solder |
Toilets Bidet Fill valves Flushometer valves Tub fillers Shower valves Shower saddles Washing machines Water maingate Vales that are 2" or larger in diameter |
- Pipes, pipe fittings, plumbing fittings & fixtures affected include both point of use and point of entry devices.
- All pipes, fittings, & fixtures used exclusively needs to be clearly labeled as illegal to use on potable service and not for human consumption.
- Human consumption includes, drinking, teeth brushing, food preparation, dish washing, etc.
- Anything installed before January 4th, 2014 does not need to be replaced as long as it meets the previous lead free guidelines.
- State and local jurisdictions may have additional limitations or requirements outside of regulations set in the SDWA.
- There is no exemption for temporary or emergency repairs.
- It isrecommended that all products for non-potable use be marked on both the packaging and the product to ensure it is no used for human consumption
