Best for 5 Extraction Laboratory Safety Practices
Footwear should always cover the foot completely. Never wear shorts or skirts in the lab. When working with Bunsen burners, lighted splints, matches, etc. Personal protection safety rules Unlike laboratory dress code policies, rules for personal protection cover what employees should be wearing in the lab in order to protect themselves from various hazards, as well as basic hygiene rules to follow to avoid any sort of contamination. When handling any toxic or hazardous agent, always wear the appropriate gloves.
When performing laboratory experiments, you should always wear a smock or lab coat. Before leaving the lab or eating, always wash your hands. After performing an experiment, you should always wash your hands with soap and water. When using lab equipment and chemicals, be sure to keep your hands away from your body, mouth, eyes, and face.
Every chemical should be treated as though it were dangerous. Do not allow any solvent to come into contact with your skin. Never take more chemicals from a bottle than you need for your work. Do not put unused chemicals back into their original container. Chemicals or other materials should never be taken out of the laboratory. Chemicals should never be mixed in sink drains. Flammable and volatile chemicals should only be used in a fume hood.
If a chemical spill occurs, clean it up right away. Ensure that all chemical waste is disposed of properly. Chemistry lab safety rules As chemistry labs are one of the most common types, these basic chemistry lab safety rules are relevant to many scientists, dealing with the safe performance of common activities and tasks in the average chemistry lab: Before you start an experiment, make sure you are fully aware of the hazards of the materials you'll be using.
When refluxing, distilling, or transferring volatile liquids, always exercise extreme caution. Always pour chemicals from large containers to smaller ones. Never pour chemicals that have been used back into the stock container. Never tap flasks that are under vacuum. Chemicals should never be mixed, measured, or heated in front of your face. Water should not be poured into concentrated acid. Instead, pour acid slowly into water while stirring constantly.
In many cases, mixing acid with water is exothermic. Before using any high voltage equipment voltages above 50Vrms ac and 50V dc , make sure you get permission from your lab supervisor. High voltage equipment should never be changed or modified in any way. Always turn off a high voltage power supply when you are attaching it. Use only one hand if you need to adjust any high voltage equipment. It's safest to place your other hand either behind your back or in a pocket. Make sure all electrical panels are unobstructed and easily accessible.
Whenever you can, avoid using extension cords. Even if you are certain that a laser beam is "eye" safe or low power, you should never look into it. Always wear the appropriate goggles in areas of the lab where lasers are present. Laboratories are used in many University disciplines. They can be defined as places of specialised research, teaching and or learning in which hazards to human health can arise from inappropriate situations and or behaviours.
Each laboratory should have either on or adjacent to its entry door a prominent placard containing at least the following information:.
Offices, write-up and study areas shall be separated from areas where hazardous materials are used or potentially harmful processes undertaken to ensure that reading and writing materials do not become contaminated. These areas should not form part of laboratory benches.
The principal objective of the WA Occupational Safety and Health Act is to promote and secure the safety and health of persons in the workplace. The employer the University has a duty of care to provide a safe work place.
Employees — and this includes students, visitors and contractors — all have individual responsibilities to take reasonable care of their safety and health and that of others, and to follow all safety and health policies and procedures.
Take time to plan your project — from beginning to end — then discuss with your supervisor and staff who will be able to help you. Check your details because:. Each laboratory or suite of combined laboratories should have its own Laboratory Safety Manual or set of manuals. Each person within the laboratory needs to sign and date that they have read, understood and will abide by this manual before being permitted to commence work.
This should also be countersigned and dated by the Laboratory Manager or Supervisor. Risk assessments determine the level of hazard or risk associated with any procedure and assess whether current control methods are adequate or need to be improved.
They should be performed when:. In research and educational environments documented risk assessments should be completed for the following:. Refer also to Section 8 of this Code. To be of a type which will afford protection of feet from corrosive or hot liquids, falling objects and other potential sources of injury.
Bare feet, thongs, sandals are prohibited. When using machinery, remove jewellery and rings. The possibility exists for such items to be caught in moving parts. Mobile phones should be used only for emergency contact while undertaking laboratory procedures. The exception is if the food and drink are specifically for research or teaching, then these items must be clearly labelled as research or teaching items.
Bandaids are available in the First Aid boxes. Use lifting devices and trolleys where appropriate. Where lifting is unavoidable, seek assistance if required share the load. Whilst using any equipment you must adhere to the standard operating procedure.
If there is a medium to high risk then safety footwear is recommended. For assistance refer to Ansell's guidance on this.
Keep benches clean and free from chemicals and apparatus that are not being used. It may be necessary to supervise contractors for some procedures. They should not be exposed to hazards. Refer to Section 5 of this Code. Regularly check disposals against licence requirements. Areas must provide suitable waste disposal containers and are responsible for their removal by an approved waste disposal contractor refer to the Chemical Safety Procedures.
Fume cupboards must be correctly operated and maintained to ensure efficient extraction of hazardous fumes and to protect operators from potential harm.
Operators should check the compliance label, the sash lifting mechanism, that the scrubber water tank is filled where applicable and availability of fire extinguishers before use. It is important to carry out pre-operational safety checks, use fume cupboards correctly and leave them in a condition which will avoid potential contamination of subsequent operators. The Standard Operating Procedure SOP for Fume Cupboards is provided to ensure correct use and is recommended reading for operators prior to commencing work.
This helpful, single page reminder of correct operation should be printed, laminated and displayed prominently at the site of fume cupboards. Growers and industry professionals rely heavily on personal experience and information from other industries e. Although hands-on experience is an invaluable source of knowledge, having scientific information to fall back on can greatly expedite the learning process for growers, both experienced and inexperienced.
A specific area in need of information is that of container substrates. Substrates can be composed of organic or inorganic components, or a mixture of both, that create the container environment in which a plant will grow and thrive.
Numerous organic and inorganic components have been used in container crop production over the years. Unlike mineral soil field soil that can be stored anywhere for any length of time and moved with any heavy equipment, soilless components must be handled as little as possible and with care so they maintain their inherent physical structures and properties. Many discussion points could be addressed in detail regarding the choice to use field soil in container production.
While it may be cheap and easily available, it does offer potential barriers, issues and even missed opportunities. Issues may include the material weight which could present lifting difficulties for your employees , introduction of weeds or disease if not properly sterilized, challenging irrigation management, variable soil types and lessened root growth compared to soilless culture.
One of the main reasons they can do this is because of the engineered soilless substrates they use to grow their crops, which are highly responsive and easily adjusted.
Many questions, misconceptions and unknowns exist regarding the soilless components used in mixes. We caution readers to be careful where they receive their information not only about substrates, but also about all topics related to cannabis production. We highly encourage cultivators to rely on scientific literature whenever possible or consult with professionals whose information comes from science-based research and experience.
This will narrow the scope of the information you find to typically more formal, scientific, published, etc. Google Scholar is also a good place to search for this type of content. Substrate quality begins at the source: We highly encourage cultivators to choose a substrate supplier there are many to choose from and build a strong working relationship with them. When looking for a substrate supplier, do your homework and be prepared to ask questions about the products and their production needs.
Ask about technical-support offerings in the event that a problem arises and you need assistance. Cost is important, of course, but that should not be the sole driving force behind the decision to choose one company or product over another. A higher-priced mix that comes with technical support and experienced grower experts is well worth the extra cost if problems arise or help is needed. As is true in many things in life, you get what you pay for.
To help ensure substrate quality and performance—substrate manufacturers and university or independent laboratories offer a broad range of testing options, which give reliable and replicable indications of the performance of container substrates with respect to water, nutrition and physical, chemical and biological properties.
Most methodologies used to develop tests for substrates over the past four decades have been adopted and modified from soil science analytical methods. Ideally, someone at every growing operation should be responsible for checking every load of substrate that is delivered to ensure quality and consistency.
If one person holds this responsibility, it improves the chances of catching inconsistencies and being confident that the substrates are correct. It is also vital that a few samples be taken and checked for pH and EC before crops are planted in the mix.
These simple steps do not require much time typically seconds to just a few minutes , but can offer grower confidence in product quality.
