A safety data sheet ( SDS ), material safety data sheet ( MSDS ), or product safety data sheet ( PSDS ) is a document that lists information relating to occupational safety and health for the use of various substances and products . SDSs are a widely used type of fact sheet used to catalogue information on chemical species including chemical compounds and chemical mixtures . SDS information may include instructions for the safe use and potential hazards associated with a particular material or product, along with spill-handling procedures. The older MSDS formats could vary from source to source within a country depending on national requirements; however, the newer SDS format is internationally standardized.
67-496: An SDS for a substance is not primarily intended for use by the general consumer , focusing instead on the hazards of working with the material in an occupational setting. There is also a duty to properly label substances on the basis of physico-chemical, health, or environmental risk. Labels often include hazard symbols such as the European Union standard symbols. The same product (e.g. paints sold under identical brand names by

The Control of Substances Hazardous to Health (COSHH) Regulations govern the use of hazardous substances in the workplace in the UK and specifically require an assessment of the use of a substance. Regulation 12 requires that an employer provides employees with information, instruction and training for people exposed to hazardous substances. This duty would be very nearly impossible without

Concern over the interests of consumers has spawned consumer activism , where organized activists do research, education and advocacy to improve the offer of products and services.

ICAO is active in infrastructure management, including communication, navigation and surveillance / air traffic management (CNS/ATM) systems, which employ digital technologies (like satellite systems with various levels of automation) in order to maintain
536-474: A notion of the consumer in relation to consumer protection laws, and the definition of consumer is often restricted to living persons (not corporations or businesses) and excludes commercial users. A typical legal rationale for protecting the consumer is based on the notion of policing market failures and inefficiencies, such as inequalities of bargaining power between a consumer and a business. As all potential voters are also consumers, consumer protection has

ICAO has been called "flawed and biased in favour of the industry" by Jo Dardenne, the manager for aviation at Transport & Environment . On 6 October 2016, the ICAO finalized an agreement among its 191 member nations to address the more than 1000 million tonnes of carbon dioxide emitted annually by international passenger and cargo flights. The agreement will use an offsetting scheme called CORSIA (the Carbon Offsetting and Reduction Scheme for International Aviation) under which forestry and other carbon-reducing activities are directly funded, amounting to about 2% of annual revenues for
1072-543: The Boeing 747 -100, -200 and -300 are given the type designators B741 , B742 and B743 respectively. Since 2010, ICAO recommends a unification of units of measurement within aviation based on the International System of Units (SI), using: Non-SI units have been permitted for temporary use since 1979, but a termination date has not yet been established, which would complete metrication of worldwide aviation, and
1139-676: The Globally Harmonized System of Classification and Labeling of Chemicals (GHS). By 1 June 2015, employers were required to have their workplace labeling and hazard communication programs updated as necessary – including all MSDSs replaced with SDS-formatted documents. Many companies offer the service of collecting, or writing and revising, data sheets to ensure they are up to date and available for their subscribers or users. Some jurisdictions impose an explicit duty of care that each SDS be regularly updated, usually every three to five years. However, when new information becomes available,

Support also comes from Canada's commercial sector with the president of the Air Transport Association of Canada saying in 2019 that "It's about safety in aviation so from
1876-636: The ICAO code for Los Angeles International Airport is KLAX. Canada follows a similar pattern, where a prefix of C is usually added to an IATA code to create the ICAO code. For example, Calgary International Airport is YYC or CYYC. (In contrast, airports in Hawaii are in the Pacific region and so have ICAO codes that start with PH ; Kona International Airport 's code is PHKO. Similarly, airports in Alaska have ICAO codes that start with PA . Merrill Field , for instance

In January 2020, ICAO blocked several Twitter users, including think-tank analysts, U.S. Congressional staff, and journalists, who mentioned Taiwan in tweets related to ICAO. Many of the tweets were related to the COVID-19 pandemic and Taiwan's exclusion from ICAO safety and health bulletins due to pressure from China . In response, ICAO issued
2010-652: The International Flight Network, Philbin refused to acknowledge the existence of Taiwan. On 1 February 2020, the United States Department of State issued a press release heavily criticizing ICAO's actions, characterizing them as "outrageous, unacceptable, and not befitting of a UN organization." The 9th edition of the Convention on International Civil Aviation includes modifications from years 1948 up to 2006. ICAO refers to its current edition of

ICAO maintains the standards for aircraft registration , including the alphanumeric codes that identify the country of registration. ICAO is also responsible for issuing two to four character alphanumeric aircraft type designators for those aircraft types which are most commonly provided with air traffic service. These codes provide an abbreviated aircraft type identification, typically used in flight plans . For example,

Each country should have an accessible Aeronautical Information Publication (AIP), based on standards defined by ICAO, containing information essential to air navigation . Countries are required to update their AIP manuals every 28 days and so provide definitive regulations, procedures and information for each country about airspace and airports.

A late draft of the agreement would have required the air transport industry to assess its share of global carbon budgeting to meet that objective, but the text was removed in the agreed version. CORSIA will regulate only about 25 percent of aviation's international emissions, since it grandfathers all emissions below

3149-1150: The following units are still in widespread use within commercial aviation: inches of mercury are used in Japan and North America to measure pressure, although sometimes METAR at Japanese airports show only hPa . Aviation in Russia and China currently use km/h for reporting airspeed, and many present-day European glider planes also indicate airspeed in kilometres per hour. China and North Korea use metres for reporting altitude when communicating with pilots. Russia also formerly used metres exclusively for reporting altitude, but in 2011 changed to feet for high altitude flight. From February 2017, Russian airspace started transitioning to reporting altitude in feet only. Runway lengths are now commonly given in metres worldwide, except in North America where feet are commonly used.
