Lab areas containing carcinogens, radioisotopes, biohazards, and lasers should be properly marked with the appropriate warning signs. Make sure you are aware of where your lab's exits and fire alarms are located. An area of 36" diameter must be kept clear at all times around all fire sprinkler heads. Always work in properly-ventilated areas. Do not chew gum, drink, or eat while working in the lab. Laboratory glassware should never be utilized as food or beverage containers. Each time you use glassware, be sure to check it for chips and cracks.
Notify your lab supervisor of any damaged glassware so it can be properly disposed of. Never use lab equipment that you are not approved or trained by your supervisor to operate. If an instrument or piece of equipment fails during use, or isn't operating properly, report the issue to a technician right away. Never try to repair an equipment problem on your own. If you are the last person to leave the lab, make sure to lock all the doors and turn off all ignition sources.
Do not work alone in the lab. Never leave an ongoing experiment unattended. Never lift any glassware, solutions, or other types of apparatus above eye level. Never smell or taste chemicals. Do not pipette by mouth. Make sure you always follow the proper procedures for disposing lab waste.
Report all injuries, accidents, and broken equipment or glass right away, even if the incident seems small or unimportant. If you have been injured, yell out immediately and as loud as you can to ensure you get help. In the event of a chemical splashing into your eye s or on your skin, immediately flush the affected area s with running water for at least 20 minutes.
If you notice any unsafe conditions in the lab, let your supervisor know as soon as possible. Always keep your work area s tidy and clean. Only materials you require for your work should be kept in your work area.
Everything else should be stored safely out of the way. Only lightweight items should be stored on top of cabinets; heavier items should always be kept at the bottom. Solids should always be kept out of the laboratory sink.
Any equipment that requires air flow or ventilation to prevent overheating should always be kept clear. Always tie back hair that is chin-length or longer. Make sure that loose clothing or dangling jewelry is secured, or avoid wearing it in the first place.
Never wear sandals or other open-toed shoes in the lab. 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. This includes any activities involving:. Work by undergraduate students may only be performed if directly supervised by a staff member or approved nominee. The second person must be competent to obtain any assistance required and to make the area safe.
If having a minimum of two people present is not possible, there are specific limitations on what types of work may be conducted when working alone. Under these circumstances there are special risks due to the lack of immediate assistance in the event of an accident or sudden illness.
This may include addressing unattended reactions or experiments. In addition, disclosure and consideration of any medical conditions that may give rise to a dangerous or life threatening situation when working alone must be taken into account. UWA Security phone offer a 24 hour escort service to vehicle or residences near the campus and also offer lectures on personal security. To request their assistance telephone allow up to 20 minutes notice for the escorting service.

Ensure that the doors to internal areas are secured on leaving. Ensure familiarity with health and safety rules and emergency contact numbers these should already be displayed in the workplace. Do not give anyone else security codes, keys or access cards. Do not provide access to buildings to unauthorised persons as Security is instructed to remove them if they cannot demonstrate current authorisation.
Report to University Security any breaches of security or suspicious behaviour. 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. If problems or inconsistencies do occur, growers should contact their substrate suppliers for a technical consultation. This is one of the advantages of buying premixed substrates from suppliers: They have technical support that can help if problems arise.
Growers who choose to make or blend their own mixes may have to find experts elsewhere to assist with the problems. Numerous professional laboratories across the country can be used for diagnostic testing of the substrate itself. Many universities have analytical labs as do many states in the U.
Current and future understanding of cannabis-substrate interactions will increase drastically as more state and private institutions are legally permitted to research and study these crops. Accurate and replicable grower trials and experimentation will also continue to provide reliable information about containerized cannabis production. Research does not have to be conducted in a laboratory. The perfect balance of science and application exists in grower and researcher partnerships, which has been the key to success for numerous other horticultural industries.
Turner Smith is a graduate student in Substrate Science currently working at the Horticultural Substrate Laboratory and can be reached at jtsmit17 ncsu. Minnesota state representative Betty McCollum tweeted this comment on Aug. He invested millions of dollars into Surterra Wellness, a medical cannabis startup in Georgia with licenses to operate in Florida and Texas, and took on the role of chairman with the company.
But what exactly were people buying? Gummies made up 30 percent of sales, while baked goods clocked in at 16 percent and dropper bottles at 15 percent. Vapes ruled the roost, commanding 79 percent of sales, followed by live resin at 6 percent and wax at 4 percent.
