For anyone in our community who does not own an Ultimaker printer, this release is a little more threadbare than our usual offerings. Luckily, we have lots of exciting updates planned for you! And in the meantime, we urge you to try out our Arachne beta. Arachne is the next evolution of our slicing engine and the more feedback we get on it before our final release, the better we can make it!
By default, tracks at a lower level in the Level Sequence hierarchy take precedence. This allows filmmakers to build a pipeline they are accustomed to, where adjustments at the shot level override the Sequence they are contained in. For example, in the video below, we have a sample scene with three camera cuts and a light pointed at, and highlighting, our Actor. Our light is set to white at the Master level. However, when we dive in and add the light to our second shot, we can make changes to it, overriding the Master level setting.

Users can further customize label rows for including other metadata elements. This image shows custom rows with rich text formatting for super-subscript, and images inserted from external files.
In the Court of Appeals litigation, AIA challenged OSHA's use of the PEL to calculate the residual risk remaining after the standard is implemented. AIA contended that workers would actually be exposed to average levels significantly below the PEL because employers would be required to engineer down to levels well below the PEL to assure that random fluctuations would not result in an OSHA compliance officer measuring an exposure level over the PEL during a routine inspection. Therefore, AIA contended, in calculating residual risk, OSHA should assume that employees will be exposed to average levels that are between one-half and one-quarter of the PEL. The Court implied that such an argument might have merit if factually supported and suggested that OSHA should make its own calculations of the relation between permissible exposure limit and the actual exposures such a limit would produce. (838 F.2d at 1266) Having carefully considered the issue, OSHA concludes it would be unrealistic to base its risk assessment on the assumption that employers will engineer to levels significantly below the PEL. First, as discussed below, the PEL of 0.1 f/cc is at the limit of feasibility for those workplaces in which asbestos levels are most difficult to control, and an assumption that average exposures will be substantially below the PEL will clearly be unrealistic for such workplaces. Second, OSHA found in issuing the 1986 standard that AIA's argument about uncontrollable fluctuations was exaggerated because such fluctuations could be minimized through proper inspection and maintenance of engineering controls and through proper training and supervision of employees whose work practices affected exposure levels. (51 FR at 22653). Third, OSHA's enforcement policy gives employers the opportunity to show that a compliance officer's measurement over the PEL is unrepresentatively high and does not justify a citation, thus alleviating any concern employers might have that they will be cited on the basis of a single measurement that results from uncontrollable fluctuations. Fourth, even if some employers are sufficiently risk-averse to engineer down to well below the PEL to avoid a slight risk of citation, OSHA cannot base a realistic risk assessment on the assumption that most employers will do so.
Accordingly, in July 1990, OSHA proposed related changes in both provisions "small scale, short duration" operations would be redefined in terms of general criteria, as well as the 1986 approach of listing specific examples. However, the underlying premise remained the same as in the 1986 standard: i.e. exemptions to the negative-pressure enclosure requirement for removal, renovation and demolition projects and limited to jobs which conformed to specified criteria. "Competent" persons, according to the 1990 proposal, were to be required as supervisors on all asbestos-related construction worksites, instead of as in the 1986 standard, that required competent persons only for non "small-scale, short term jobs." Required training for competent persons, would vary, however, depending on the kind of asbestos-related job needing supervision.
OSHA proposed in 1990 to expand the requirement. Under the proposal, supervision of all asbestos construction worksites by a "competent person" would be required; the training of a competent person would be keyed to the kind of asbestos operation. However, the proposal left undecided whether onsite, continuous supervision of all asbestos-related work would be required for all asbestos work. The final standard resolves these issues. A "competent" person, as defined in the general construction standards, must supervise all work under the asbestos construction standard. That person must be "capable of identifying existing asbestos * * * hazards in the workplace, and has the authority to take prompt corrective measures to eliminate them * * *" 29 CFR 1926.58[b].
OSHA reiterates its statement in the proposal that "all construction site employees would benefit from the presence of a competent person to oversee asbestos-related work" (55 FR at 29726). However, the need for on-site supervision varies with the hazard potential of the work undertaken. All workers performing Class I construction work must have continuous access to an on-site supervisor, who meets the training requirements for designation as a "competent person" under this standard. Supervision for Class II and III work does not always require a continuous on-site "competent person," therefore the standard requires inspections at "sufficient" intervals and at employee request. Supervision of installation of asbestos containing construction materials and Class IV work must also be accomplished by complying with the "generic" requirement for "frequent and regular" inspection [Paragraph (0)(2)].
Training for "competent persons" can be accomplished in a number of ways and meet the standard's performance requirements. For Class I, II and III work, the "competent person" must take a course such as a course under the EPA Model Accreditation Plan for accredited contractor/supervisor, project designer or management planner course, or their equivalent in content, duration, and criteria for success. Class IV work may be part of larger construction projects, in which case the competent person trained to supervise the project should supervise the on-site cleanup activities which constitute the Class IV work.
Included in the construction and shipyard employment standards is a definition for the term "closely resemble," which is the term used in the regulatory text to limit the use of historic exposure data to predict exposures. It is defined as circumstances where "the major workplace conditions which have contributed to the levels of historic asbestos exposure are no more protective than in the current workplace." OSHA's intent is to allow data reflecting past exposures to be used to predict current exposures only when the conditions of the earlier job were not more protective, i.e., employees were not better trained, work practices were not used more consistently, and no more supervision was present.
The revised definition deletes from the definition a list of duties to be performed by the competent person. Duties are more appropriately set out in other regulatory paragraphs which are prescriptive, rather than in the "definition" section. In response to the court's remand, OSHA has also expanded the scope of the competent persons's duties so that a competent person must supervise all asbestos activities under the construction standard. As noted, these requirements are set forth in other regulatory paragraphs which govern conditions of work in covered activities.
In addition, paragraph (d)(3) sets forth the duties of the employer of employees who are exposed to asbestos hazards, but who did not create the source of contamination. One, such employer may request the contractor with control of the hazard to take corrective action. For example, if there is a breach of an enclosure within which asbestos work is being performed, the employer of employees working outside that enclosure should request the asbestos contractor who erected the enclosure to repair the breach immediately, as required by paragraph (d)(2). If the repair is not made, and if employees working outside the enclosure are exposed to asbestos in more than de minimis amounts, the employer of those employees should either remove them from the worksite pending repairs, or consider his employees to be working within a regulated area and comply with the provisions of paragraph (e) governing exposure assessments and monitoring of employees who work within such areas. If the employer of employees exposed to asbestos because of the failure of controls installed by another contractor, is the general contractor of the construction project, as such he has supervisory control over the entire worksite including the regulated area, and is responsible for violations which could be abated or prevented by the exercise of such supervisory capacity. 2ff7e9595c
